About a month ago I started a small community 10 gallon tank. Yesterday I moved the community into a new 20 gallon tank. It’s currently stocked with 1 tetra, 2 guppies, 2 Dalmatian mollies, 2 black mollies, 1 assorted yellow molly, 1 sail fin molly, 1 balloon molly, 2 sword tails, 3 kahaku swords, 2 mystery snails, 1 assassin snail and 2 shrimp. During this time I think the guppies had a couple babies that I’m now raising in a separate small tank and the shrimp had babies too! I collected about 8 of them. The two mystery snails I put side by side after transferring them into the new tank because I wanted them to go into together. Not 5 minutes later I looked and found them connected. They’d never done that before after a month in their 10g. Now I’m worried they’ll have offspring. I don’t want this tank to become an infestation of invertebrates. Over night, I was thinking about removing them all before they multiply again; just doing a strict fish only community tank. I’d like to hear others thoughts and advice. Thanks.
