Well all my little snail babies are in my 25 gal tank, but I also have 1 betta and 1 mystery snail in a 2.5 gal tank. The betta has been looking poorly lately and I've been wondering why, and then tonight after I dropped her food pebbles in the tank I think I figured it out. The snail immediately went up and ate all my bettas food! He has his own food, which he likes, but he is eating the bettas food too! He's starving the poor thing out! Grr. I am not pleased. I put some flakes in Nd the poor betta was able to eat some, but a more long term solution must be found. I just wanted to vent my frustration on my poor bettas behalf lol.
