I had three angelfish in my tank. Two had paired, and upon coming home and seeing the two lay/'fertilize' eggs, I was 100% sure which on was not in the pair, so I moved him/her to another tank. Last night before I went to bed, I saw where the pair had laid more eggs, but this morning I noticed the two fighting quite a bit. If they just laid eggs, and I removed the other male/female, should I be concerned that they are fighting? I saw yesterday evening (perhaps after the eggs were laid) that they were 'kissing' which I know is a little bit of fighting, but this morning were turning their bodies and darting at each other very aggressively.
