We have a 25 gal (tall) planted tank with cardinal tetras (5), german blue ram pair, rasboras (6) and some pepper. It's been a while since we added new fish and some old ones (tetras) have died. My wife wants like them black mollies... I am just worried about their well being in fresh water as they are brackish water fish. I heard they can be adapted,but I'd like my fish to be well rather than survive..... Any thoughts? TIA

I dont have much experience with mollies but i have a friend that has been keeping fish for over 15 years and i have seen his tank with black mollies and its fairly clean, the fish look happy and have been there for quite a while and are fully grown. I dont think that adding black mollies to your tank will be a problem but in my opinion they look really nice and are a good addition to any tank .

hope i helped you a little and you can find some more info on this topic .

Generally mollies need a bit more footprint in a tank. What about some platies?

By footprint you mean swim area? I am thinking for shortfin mollies 25 gal should be OK... It's the sailfin mollies that get much bigger.... no?

It's the length and depth of the tank. A 20 long is generally minimum tank size for mollies who are very active fish and grow to 4".
