I have a 20 gallon long setup. Planted and DW. All I have is 3 dwarf gourami's and 2 mystery snails, how many Cory Cats could I put in my 20 gallon long. Or how many would u recommend?
As I investigated I found out they do best in small groups, of 4-6. Wha'ts too much for a 20?
And I got a 10 gallon tank with 6 tetras and 2 mystery snails. I want to throw 2 Cory's in there too. Is that ok? How many's too much in a 10 gallon too ?
Thanks for your help in advance
