I wasn't planning or had any interest in keeping flowerhorns but I was given a pair because the previous owner can't keep them any longer so I toss them in a growout tank. I wanted to keep them separate cuz I thought they are aggressive but I have no capacity to manage an additional two tanks, right now they are doing fine with an oscar, tsn and pleco. The Flowerhorns are around 3-5 inches and this morning I saw eggs under the driftwood with the smaller fish guarding it meanwhile the larger one had his fins tattered a bit and was suddenly territorial against the oscar which was not the case before, could he be protecting the eggs?? I don't even know if they're fertile and I have no prior knowledge in breeding fish. Should I move the rest of the fish out of the tank and leave the pair or should I transfer the eggs on a smaller tank with airstone and should I put the pair of fish in or just the eggs? Also are they fertile?
