Yessiree! This is perfect in size and material!!
Size: 6.5 gallon
My big boy betta and I are so happy with this tank!! Hard to find ones that aren't glass and that are decent in size without breaking the bank. Kudos to Koller for the packaging it came in!!! I was so worried that it would be scratched up in shipping. No way it could bed!! Finally - a company that respects what they make and knows how to package it!! Due to my own preference, I did make two adjustments. The filter hangs a little funny I think so I used a piece of hard foam where it sits to shore it up right. Perfect now. Also used hard foam around the light cover to heighten it. Again, only due to my personal preference. Thank you for an absolutely wonderful tank Koller! It's honestly just what I was looking for! ... show more

Great fish tank 3 gal.
Size: 3 Gallon
Easy set up. We went from 1 gal to 3gal. Love the light system switches colors has a timer. Pump seems good. No issues. Good size for my 6 yr olds room. Had it a week no issues. fish love it! Bought all the interior stuff minus the submarine for $10 on Amazon. I added the bubble machine bcz I had one. 3/20/24 update we love the tank fish are doing well. The light under the hood stopped working so that was disappointing. I see water condensation under the plastic cover not sure if that’s the issue. However I called support the lady asked a few questions and said she’s sending me a new light strip. So that’s good hopefully this one lasts longer. But Koehler service is great! Update 5/23/24 now the new light stopped working only after 2 months. I’m going to call again but it looks light this is defect in this fish tank. ... show more

Replacement items
Size: 6.5 gallon
Koller Products sent a replacement filter and light strip to me. The filter is working very well - no noise and less heavy water flow. The fish are swimming about more. I don't know how to remove the cover over the light strip yet but I hope to figure it out soon. I am excited to try to install it tomorrow. My appreciation of the tank has risen back to what it was initially. It is attractive and a great size for someone who doesn't want a larger tank. Thank you Koller Products. Your customer service is terrific. I ordered this tank back in January. The pump didn't work and all of my fish died. And then I broke my ankle so it was 8 weeks until I could drain the tank and clean it. The company sent a replacement pump. When I was free of the cast and then the boot I set the tank up again. The filter shoots the water out and it's noisy but it does work. At no time did I turn the light on. Guess what??? No blasted light so I can't see the fish that I bought today. The betta disappeared; I guess the water flow is too much for it. One of the neon tetras is gone already - less than 1/2 hour after I put them in the tank. This sucks! Today is the first day I've been able to go to the store since January. Within the next few days I think I'll drain the tank, flush the fish and put the tank out for the trash. ... show more

Faulty Aquarium Filter
Size: 6.5 gallon
The tank is beautiful and very nice, we like the shape of it, but I hate the timer on the light. I did not realize the light was on a time when I purchased it or I would not have bought it. I turn on the fish tank lights in the morning and turn them off at night before I go to bed. I also use it as a reminder each morning that I fed the fish. With this light turning itself off after a couple of hours I sometimes forget if I fed them. Also, it leaves the fish in complete darkness all day/night long. The filter that came with this however is horrible. It quit sucking up water and the filter was bone dry after 3 days of usage. It was making a very awful noise as the pump tried to work. I tried re-filling the filter but the water wouldn’t stay in it. It is very weird but now I have to spend the money to go buy a new filter because the fish can not be without. After purchasing a new out-of-tank filter I realized there is a big bulge on the back of the tank where the filter should go, meaning the new filter can't sit nicely on the tank. Most tanks are flat all the way across on all seems. Not this one, so the new filter has to rest against the wall on the top of the tank making things very awkward. I've grown to hate this tank and cannot recommend it. You can't change the accessories (filter) easily and timer for the lights is just flat out annoying. ... show more

Highly recommend
Size: 6.5 gallon
Beautiful and an amazing value! I keep bettas as a hobby (and pets) but the inner child in me has always wanted glofish! So the number of color options and easy viewing angles w/this tank was ideal for me. I was concerned w/some of the reviews stating that there was no cover over the lighting causing rust and shortages. As the lightning was going to be tge main reason for me to purchase I was pretty nervous. However my hood has a thick plastic shield secured over tge light strip (perhaps they've made upgrades?). Its great that it comes with a filter as an almost all-in-one tank, especially if you're new to the game. However i wasn't a fan. It's an unusual and awkward shape and just doesn't seem like the right fit for this size tank. Over the yrs I've compiled extra everything, including several filters, so i used one of my own that blends almost completely into the background. If you don't have extras tho i imagine the one included would work just fine. Less money to pump into equipment. Like other reviewers, the acrylic did have some scuffs, but i expected that having used acrylic for some time now. Some scratches wiped off but ultimately when its filled with water the scuffs are virtually non existent. The hood is great. It has a nice weight to it which is important for me since i have a cat, and i like that it doesn't "attach" to the tank with clips etc. But rather has pegs to rest in specific grooves of the tank, making it easy to open and close for water changes and feeding, but still one less thing to break. ... show more

my take as an experienced fishkeeper
Size: 6.5 gallon
I can’t lie, I have very mixed feelings about this tank. We’ll start with the positives: 1) plastic makes transport easier as it is much lighter than glass/eliminated other drawbacks of glass such as seals weakening or stress cracks over time. the only drawback is the likelihood of scratch marks appearing from cleaning, gotta be careful with this tank. 2) the filter not being built in gives me the ability to easily replace if it gives out. 3) filter is relatively gentile, I specialize in bettas and my female does just fine, I would NOT recommend this for a long finned male, they need water more still than what this filter would allow. i personally think it circulates and filters the entire tank just fine. some negatives: 1) my BIGGEST frustration with this whole tank is the lack of ability to install your own lighting timer system. I have several tanks, all of which run on a 12hr on/off timer. i use the same type of timer for all of them. i cannot set this built in one to a 12 hour setting (max of 8), so i was forced to purchase a timer anyway (not a big deal, i expected to need to do this anyway). however, that does not work either. the lights do not come back on when power is cut (via unplugging or the timer auto off switch), it must be clicked back on manually. i have tried both a cylinder jack plug timer and an outlet timer. neither work. i must say, that design feature makes me straight up furious. i need to purchase an entirely different lighting system now, simply because the designer failed to consider anyone who might want to operate their tank with their own timer or schedule! ugh, moving on… 2) yes, the filter does suck a little. i know most negative reviews are about the filter and frankly, a lot of that is user error. as a professional in the industry i see that a lot and often ignore certain reviews because of it. so here’s my take: if you follow instructions, it’s honestly not that bad (so far, tank has been running for a little over a month). sometimes it gets air pockets stuck between the filter cartridge and the filter itself and will make noise. i just lift the cartridge and shake it a few times and it stops. this doesn’t happen crazy often although it is annoying when it does. DO NOT fully submerge the filter, most of the people who complain about malfunctions have it fully submerged. however, this leads to my last point… 3) i don’t love that i cannot fill my tank all the way. it’s a 6.5 gal but my fish only gets about 5.5-6 gals of swim space because of how low i have to keep the waterline. i normally prefer to fill my tanks as high as i can without getting filter backflow…well you can see in the pic how high that is with this aquarium and filter. Overall, i do like the tank, but i wouldn’t purchase again. it is mainly that damn lighting system, the manufacturer needs to improve that. filter could use some work too. aside from that i really can’t complain too much. seems fairly durable, spacious, my new girl mango is thriving. ... show more

GREAT OPTION TO CONSIDER!
Size: 6.5 gallon
VERY NICE Beginner's Aquarium! Large enough to enjoy creating a nice bioscape or artificial landscape for your new community tank! As goldfish must be in a separate tank than my very large Angelfish community tank, I am choosing to use this tank as a separate aquarium for my 2 small, young gold & black calico fantails. Adding 2 Nerite Snails complete the natural setup views. The built in light works very nicely with the flip open tank lid making access to the ENTIRE aquarium for feeding, cleaning and using tools to reposition tank items easy and carefree! The filter is quiet and hoping replacement filters are easy to order and reasonably priced on Amazon. The only downside, if you could call it that, is that you'll need pliers to break off the tabs allowing extra openings to the lid for a submersible heater, LED Bubbler lights, etc. I highly recommend this sturdy, plastic tank for both beginners and those looking for extra tank setups at a convenient price. ... show more
