Right now I have 3 female mollies in my 10 gallon tank. Wynnie is around 2", Skittles is about 1 1/2", and Pipsqueak is probably 1". I'm going to be moving them to a 29 gallon tank in about 3 weeks when I get the stand. I'm wanting to get one more fish to go with them, but I don't know what kind I want. I want to have my tank pretty understocked for the inevitable Molly babies. (Skittles should have hers probably within a week.) I'm not planning on removing them, but I'm thinking that some will probably survive.
Anyways, back to the point. I want to get a fish that's cool, will not be aggressive to my Mollies, and is perfectly fine being the only one of its species in the tank. It also needs to be able to be in a 29 gallon with 3 mollies (so far...) and not take up all of the room. And of course, I don't want my girls eaten.
I keep my mollies in 78 degree water, with 2 teaspoons per 5 gallons of aquarium (NOT marine) salt.
So, does anyone have any suggestions? Remember, I still want my tank to be understocked after I add this fish.
