    • A perfect little desktop aquarium.
Size: 1 Chamber Color: Black
Review Image by A. L. Lindsay

Review Image by A. L. Lindsay
The tank is perfect for both my desktop and Betta. The filter output is not too strong for the Betta. The Betta is able to rest on the Amazon Sword leaves, as well as in different locations around the tank. (Others here have posted how to reduce the filter output if needed.) I added a Hagan Marina reversible aquarium background. I did not use the adhesive sealer, as I prefer a more subdued background. I added one Amazon Sword, one Marimo moss ball, gravel and a few rocks for the in tank decoration. The pump is essentially silent. You have to really pay attention when all else is quiet to hear it. That is a huge plus for me. The plastic is crystal clear and I love the rounded edges, but it is plastic so I'll need to be careful not to scratch it. The dark rocks are a few from the ones I had in the base of the Betta's old bowl. After moving the Betta to a cup, I stirred around the old water and rocks vigorously, let the silt settle, and then poured the water in the new tank to provide a starter for the beneficial nitrifying bacteria. After a while I'll add some ghost shrimp and possibly five or six Ember Tetras. (I know the Tetras are pushing it, especially since the tank doesn't have an under gravel filter to increase the nitrifying bacteria colony. But my Betta seems to be a woos, so I may try it and pull them if the chemistry goes awry). The only thing negative I have to say about the unit is I wish the cord that goes from the pump to the light was twelve inches longer. That would give me ultimate flexibility in positioning the pump. But I can make it longer if I want and it works fine for the decor I'm using now, so it's not a big deal. I'm not worried about finding a replacement filter. On tiny tanks like this I generally don't use the filter that comes with it or I modify the filter so I replace only half the filter at a time. Of course I have to change out the filter halves more often, but since I often push the capacity of a tank this allows me to keep more of the benefit of the nitrifying bacteria that colonizes the filter. Even if you don't want to go to this trouble, the filter has a sponge pre-filter that comes before the main filter that holds the activated charcoal. Just don't rinse out the sponge at the same time you change the main filter and you'll keep the a solid colony of the beneficial bacteria anyway. UPDATE: A month or two after setup, I added a small albino plecostomus (~1"), two ghost shrimp (~1" each), and one cherry red shrimp (~1/3"). I have not changed my feeding routine of two Betta pellets three times a day, with an occasional third pellet added. All are thriving. The shrimp have all molted at least once. The tank is algae free. The bottom is free of visible detritus. The Amazon Sword put out a rhizome, which I anchored in the opposite back corner. The sprout is now a little more than half the height of the aquarium. I couldn't be more pleased. ... show more

    • Great Betta Tank
Size: 1 Chamber Color: Black
I've tried so many different tanks over the years, this has been the best for my bettas. I've gone up to 5 gallons for a single betta before. The fish were less active because the size filters needed to keep that much water clean caused a strong current that impaired their swimming. They spent most of their time wedged in a plant and only ever swam to eat or surface breathe. Even buying larger tanks supposedly made for bettas didn't help because they had the opposite problem. The current was so weak the water wasn't being pulled through the filter properly and in no time I had water quality problems. Sick fish from dirty water are not happy fish. This tank is a completely different story. I put a bit of filter floss in the intake and output of this filter. The filter is still able to keep the water clean but the current is so mild my bettas can swim. They swim regularly now and seem to rest on the plant leaves instead of using them as an anchor. Weekly partial water changes and routine cleaning are a breeze due to the size. I like that the light and filter use one plug. That means I can use a standard extension cord with the single filter-light plug on one side and the heater plug on the other. It's a space saver that easily fits behind the bookshelf the tank lives on. This also means the light is on the outside of the tank. Which is a great feature! I can't tell you how many times I've had to replace lights that are on the inside of the tank. In no time they get condensation inside them and stop working. This light never gets wet and I suspect it will last the lifetime of the tank as a result. For replacement filters, I use Top Fin Retreat 2.5g cartridges. They come in packs of two. I had them leftover from another tank. They are too tall for the filter out of the box but cutting them in half makes them fit perfectly. So you get four per box instead and it comes out to a dollar a month per tank. The only thing I don't like is there are cut outs near the top of the tank. I think it's supposed to make it easier to remove the lid from the tank. It's already easy to remove the lid so they are not needed. The cut outs lower the water level you can have in the tank and the fish could jump out if it was determined. I put a clear piece of tape over the holes as an easy fix. It would be nice if these were removed in future versions. ... show more

    • Perfect for my Sea Monkeys
Size: 2 Chambers Color: Blue
I got this to upgrade my sea monkeys from their original Ocean Zoo tank. It's the perfect size, and they are thriving. Took off one star because the lid is hard plastic, and not able to cut notches or anything in it for the bubbler's air line tube or the heater cord. I tried, and it cracked across the lid, not just the edge. So the lid just sits up in the back on top of the wire & tube. Otherwise, the tank looks great, and my sea monkeys love it. Price was excellent too! (PS. DO NOT PUT BETTAS IN THIS, IT IS MUCH TOO SMALL) ... show more

    • Perfect little tank for my betta
Size: 2 Chambers Color: Blue
I’m using this tank for a single betta, and it’s the perfect size! It looks nice and is easy to clean. The included plants add a nice touch, and my betta seems really happy and active in it.
