    • Worth the Money - Long As You Set It Up Right Worth the Money - Long As You Set It Up Right
Style: LED Lighting Color: Black Size: 8 Gallon
Review Image by Harp Gal
Review Image by Harp Gal
Meets every expectation! Most beautiful aquarium I've ever owned! NOTE - I have 20+ years experience keeping fish. But after reading so many negative comments (most of which are on the silver MCR-light version), just to make sure, I talked with my local fish store equipment experts to make sure the little guys in my current tank would transition ok to this new tank, before I even bought it. Here's my advice: Regardless, buy the air stream cap!! It's only $2, & it will make sure nobody gets stuck in that tube! (See newer pic with assassin snail). -If this is a brand new aquarium for you, I would set it up according to the instructions. *Yes the air pump will be loud if it's right next to the surface the tank is on, as it vibrates. I recommend putting the BiOrb on a cabinet/stand with a drawer/shelf inside that you can put the air pump in (with a hole in the back for the tube to connect through). *Keep in mind most tropical fish need a heater (yes the tank lid has space for its chord), so I would buy one. If you don't want to buy any decor not sold by BiOrb (like live plants & wood), you'll need to start slowly with your fish. I would add any bottom feeders (shrimp, snails, ottos) on the 1st day that you can add fish, & NOTHING else. (BiOrb DOES NOT recommend corys with their pebbles just FYI.) Wait another 2-3 more days, then add your other fish. Stay away from micro breeds & any digging breeds (again due to their pebbles) and don't overload the tank. The general rule is 1 inch of fish = 1 gallon of water. This model is an 8-gal tank, so no more than 8 fish total. Again, talking with your fish store expert will help. If everyone's happy in 8 months, you can be more flexible with this. -If you are transitioning fish from an old tank to this one, this will work great. Don't use the fake pebbles that come with the tank if you're fish are smaller than 2". These pebbles are large & oddly shaped (& this is why small fish get stuck in the filter). Use standard, large aquarium gravel, or river rocks as I have here. The goal is to cover the filter enough that no one will get caught inside, but there will still be flow. Sand is a no-no as it will get stuck in the filter. If you use substrate, you'll want to use it in combination with something else, & position it away from the filter. You might need a bottom feeder fish if you don't have any, &/or don't want to clean the tank with a gravel vac as the filter will work slightly slower with smaller gravel just FYI. As my picture shows, I've already moved all my rocks, wood & live plants to the new tank right away. I recommend this (your fish will be fine without decor for the 3-day period the BiOrb needs lol). This will establish the healthy biome faster, & prevent ammonia spikes when the fish are moved over. If you have a planted aquarium, I would move some, but not all, of that so neither tank's biome gets messed up. Also, I'm not using the water bio booster (that comes with) because I have live stuff already in the tank, again to prevent ammonia spikes. And I have my own water conditioner my fish like, so I'm also not using the one that comes with it. Hope this calms some nerves! This really is a beautiful aquarium, my fish will love it!! ------- Update 2/23: Still love, love, love this aquarium! It took a few months to get the ideal balance between fish, decor placement, & cleaning (this is an 8 gallon, my previous tank size for over a decade was 5 & a completely different shape/setup)... But I expected that. Currently it has: Cardinals, a couple danios & platies, a licorice gourami, that snail, & two amano shrimp (one of which is preggers, so yeah everyone is pretty happy lol). ... show more

    • Worth the price - Happy Fish
Style: LED Lighting Color: Black Size: 4 Gallon
Super easy to put together. My fishes are very happy and more active. They actually go round and round. Kinda bummer that you have to buy operate decor tho. Pricy but very pretty. Worth the price.

Style: LED Lighting Color: Silver Size: 4 Gallon
This is so incredibly loud! It looks great but I have the filter off most of the time because it is so loud and it seems to bother my fish. She seems stressed out when I have it on. I think I’ll be looking for a different brand. Not worth the money!

    • Fun Little Tank
Style: LED Lighting Color: Black Size: 4 Gallon
Fun little acrylic fish tank. The bowl type shale makes it really unique to look at and throws off the perspective of what's inside. A little too small for most fish, but some small shrimp or maybe even micro crabs would do wonderful in here. I have mine planted with aquasoil and some easy to grow plants. The LED light is plenty for basic plants. The filter also works well, but be warned it's on the same outlet as the light, so you can't use a timer without having the filter go off at night. This is actually how I have mine set up as I don't have any fish/critters in the tank right now. I'd definitely recommend getting it while on sale, because the price is a little steep at full price ... show more

    • Look cool but
Style: LED Lighting Color: Black Size: 4 Gallon
The design is great but not adequate for a betta. Design promulgates algae growth if not careful, hard to clean round surfaces. All accessories are double non biOrb equal products filter change is easy to change. Need valve adjusters as flow too strong. Decor offered leaves no room for fish to swim so limited that given rounded surface. Cool to look at but would not buy again. ... show more

Have had aquariums for decades and finally decided I was done with them about ten years ago. Got this for Christmas and was happy. It’s an amazing piece. The round shape is different and attracts a lot of attention. The bubbler and heater are very quite and my fish (Frankenstein, because he’s alive after shipping from CA) is healthy and happy. ... show more
