I have a 2-inch albino rainbow shark, GloFish, a pleco, neon tetras, baby angelfish he's around 3 6 months old, mystery snail, snails, ghost shrimp, and 3 albinos that look like baby sunshine peacocks but with no stripes or green if u know what they are please tell me their fins are dark on the ends like bronze. They live all together in a 25 gallon for now peacefully. But I'm looking to get a bigger tank in the next 3 months or less. I was just hoping for some help at what size of a tank to get them next. Also, would my red claw crab be fine with them in the new tank? Ik he will eat the snails and shrimp but what about the fish?
