Is it alright to keep a small Jardini by itself or should it have 1-2 tank mates that are bigger than it? Right now I have him in a 60 till I get a 180 or 200+ later this month. He's about 3-4" and as of now he's with a 5" clown knife and a 7" senegal. However, everyday when I wake up I see him with white dots on him which makes me wonder if it's the clown knife picking on him or possibly ick. I'll post some pictures tonight.
