Question
can i keep baby goldfish with 2f and 1m balloon mollies in 20gal aquarium
and how many ?

or can i keep 2 mystery snails with them

Answer
Hi Wajid;

Goldfish are coldwater fish and mollies are tropical (warmer water) fish. They should not be in the same tank together. You can keep mystery snails with mollies though.

Goldfish are very messy fish that very large. You could keep two goldfish alone in a 20 gallon but that's all you can safely have in there. The goldfish will grow to be over 6 inches long and need all the space to themselves.
