Hello! I've got a male sailfin molly with some white cloud minnows in my Q tank right now, and I've got just a couple questions: How large will a male sailfin ultimately grow? (He'll be in a 75 gallon tank after quarantine.) AND Can I feed him sheets of marine algae as his primary food? You see, he'll be in a tank with a dozen long finned danios after I move him; and they are very aggressive eaters! I want him to get enough food, so I was wondering about the sheets of marine algae. I don't THINK the danios will eat that, but they will eat just about anything I guess! Thanks for your help!
