Great for my hermit crab
Iâm very pleased with this little tank. I bought it for my hermit crab, and itâs the perfect size / shape (longer than it is tall). It was long enough to do sand and peat and hold a food bowl, a saltwater and freshwater pool, as well as some toys, shells, and plants.That said, I canât speak to the filtration system, but I do keep fish as well and canât help but think this is too powerful for a tank this size. I truly think it would likely kill the fish (and the tank is fairly small for a fish of any time anyway).In short, this makes an excellent terrarium for plants or crabs or perhaps a small reptile, but Iâm skeptical of its functionality as a fish tank. Still, five stars for my uses.

Adorable Betta Tank!
This little betta tank worked perfect for my needs! The size and depth is perfect and my betta is so much more active now that it is not as deep but much wider than his previous tank. The lighting is a little low, I wish it had the puck light in both sides of the lid. Leave it off during the day and on at night and it would be the perfect childs night light! It is small so really only good for a betta or maybe some shrimp or a few small neons, nothing larger than that. The filter is a little strong for a betta so I just put his sponge filter in and will use the one that came with it on the larger tank. All in all I am very happy with this purchase.

Not good light to much power abd can not be adjusted and filter not great either.
So, gravel doesnât even cover the bottom all the way. The lid has a small gap which isnât to bad but I have a crayfish baby in the tank and any crack is not good. The filter, very strong maybe to strong and the air line adjustable knob didnât work on mine at all so I just capped it and the second opening to make the flow lower and hopefully not to strong for crayfish. Will try and update again in a few weeks.So, update is not a good tank the light that comes with it is to stronge and causes green algae to grows the filter wasnât really great either. I changed filter to try again but no luck and now I am buying a whole new aquarium and trashing this one. I was having to change and clean the tank more then a week about ever 4 days a all I have is a baby crayfish in it.

Great size, plastic not to clear
Perfect size for a beta. I have plant growing out of it also. everything worked well. Only down was that it doesn’t seem very clear. Glass would be clearer but I’m a safety first gall.

Perfect tank size.
Fast shipping well packaged, great tank. This is a great size for this tank. The dimensions are great for a betta and a few friends. Iâm not crazy about the items that comes with this tank Iâm just interested in the fish tank itself. Itâs a good size for me to make a planted ecosystem for my little friends. A few dyi adjustments and itâs perfect. Will update this when itâs all done.
