Hi! I’m Jennifer. New to fish keeping. 20 G with otocinculus. Have 2 females with eggs and one male. Last few weeks they have been laying eggs. I realize that am quite lucky, since I’ve read it‘s a rare thing. I did not intend to have fry but want to do all I can to keep them alive. Currently, I wish to learn more about treating the tank for worms/parasites. Not sure what I have, There is a lot of info on the web but I’ve found it to be confusing and I’m wanting clear advice from experienced hobbyist not to wast time or money. Also looking for advice on what to feed the fry.
