Well I was just cleaning the tank and I notice these small swimming things and it was samll guppies. What do I do with them? I only have 1 tank and its a 60 gallon tank with other fish in there like koi,mollies, and a pleco. What do I do? I want to save them all. If I buy alot of fake plants or give them a place to hide will it save them? What should I do?
