So I got 5 harlequin Rasboras about a month ago. They are all schooling tightly, very active, and eat very well. However when I fed them this morning one had what looked like a tumor on his side just under his dorsal fin. I don't know if it was there before I noticed it today, but he is still super active and eats really well so I don't know if it is really a problem. It sticks out about a millimeter or two. They're in a 29 gallon filtered heated cycled tank. I do a 20% water change twice a week. In with them are 2 mollies, a blue gourami, and an albino Bristlenose pleco. Any ideas if I need to be worried and if so what to do about it or what it is?
