2 Buddies by Dch48 posted Apr 16, 2018 at 3:44 PM I have a Topfin 3.5 gallon tank with a Halfmoon Betta in it. It has been set up for 9 days now and he's doing fine. He went in the tank about 3 hours after it was filled and the temperature stabilized. I conditioned the water with a Tetra Complete Water Care Kit and also added some TopFin bacteria supplement. The water clouded a bit on the second day but cleared up on it's own. I have done a one gallon water change twice so far and everything seems fine. I do not have any testing kits though. He has 2 tankmates. A Mystery Snail that is very active and a small Nerite that moves around very slowly. I fed the Mystery snail a crushed pea and he finished the whole thing. The Betta is kind of picky. He will not eat any kind of pellet food, he spits it out. He will only eat flake food that is crumbled into very small pieces with some crumbled freeze dried bloodworm added. He also eats frozen brine shrimp. I turn the filter off at feeding time and he cleans up practically everything with only a few small pieces falling to the bottom which I'm sure the snail cleans up. The Betta will also go down and pick at the gravel and follows the snail around. I only put a few pellets in every so often so the snail will get more food. I also put in a Marimo moss ball. I'm wondering if I should do another water change (it's been 3 days) or if I can now do one once a week. A full third of the water gets changed out. Here's a pic of the 2 friends foraging at the bottom.
