I have a ten gallon tank with 3 small mollies, 1 sunburst platy, 2 ghost shrimp and 1 snail. First does that sound too crowded? They are all very tiny at the moment. One of my ghost shrimp just hides, doesnt move that often. My main concern is my sunburst. She just swims up and down the glass staring at her reflection and doesnt interact with the other fish. Do they not get along? There is no sign of aggression by either species, they just leave her to her swimming but I feel bad. Should I add another one like her in there? Also my snail is a gold mystery snail. Some people said they are asexual.? Thanks for all the help.
