I think my blue-blushing angelfish is pregnant! I observed a small "tube" sticking out of her belly. She and the other golden angelfish became strangely aggressive - they chase my neons around! This never happened before. Could it be a protective behavior during breeding? The other thing, which is very strange, is that the golden angelfish also has a very, very small (hard to spot it) tube under her belly. But it is nothing compared to the blue angel's tube. So now I am confused. Do males also develop some tubes, only smaller ones, during breeding? Or do I have 2 females? Can 2 females alone lay eggs, even if there is no male in the tank? Or is my golden angel a male? I am pretty sure at least one is "pregnant" because in addition they both swim around my amazon swords and "clean" them. They also clean the filter and heater! I really don't know what to do! I put the two angels in my 10 gallon tank, just in case, and provided some decor tilted diagonally because I heard they lay eggs on diagonal or vertical surfaces. Is there anything else I should do? How to care for anelfish fry? I have absolutely no idea what to do, and no experience whatsoever! Though the eggs will probably be eaten by the parents ... or if not, they probably won't make it anyway, right? I don't have any special breeder tank. In my 10 g. tank where I put the angels, there is a WhisperTetra filter (flow is quite gentle) and a fine black gravel. Should I increase the temperature? To how many degrees? HELP!
