HI all! I have a small freshwater tank with 2 black mollies and 1 sailfin molly...I added some salt to the tank as recommended and the fish are doing great (all female) and the fish store that I go to said most other fish would be ok with that amt of salt (1tbsp per 5 gallon) since it's so little in comparison to what salt levels could be. I've generally found that there's SO MUCH contradictory info out there so I am using people's experiences here along with my fish store to figure out how to best keep my fish happy. I have my 3 mollies in the 10 gallon, as I mentioned, and they seem to be enjoying the space. I don't really think I want or need to add anything else in there since I don't want to overcrowd and they are just so happy. I can't really imagine where anything else would fit! I don't know. I want fish I can upgrade to a 55 gallon in the future and now I'm worried that the mollies won't be happy with anything else (opinions on a species only molly tank?). My LFS said they are passive fish though and as long as they have company they'd be fine. Not sure what to do... ???
