I noticed this morning that my danios were more active then usual ( is there such a thing lol) anyway so i stopped to watch them and noticed that two of them were colored up, had more red in them and one was not and the other two were chasing her, so i presume they are trying to breed. my ? is I have a 5g tank not being used, should i put the three of them in that tank, then if they lay eggs, should i then take them out, i read they will eat thier own eggs. i would like to try to raise thier fry. any suggestions?
