So I've kept Discus for a little over a year and a half now, I've collected 9 over that time. The first Discus I ever got happens to be the most dominant, and he paired off with another Discus I have in the group. When they choose a territory, he gets extremely stressed out with others trying to eat the eggs, and chasing people away constantly. In reaction, he his the Alpha of the group, so he does take a bit of a beating compared to the others in affect, with the added on fending off the eggs with his mate. He's gotten secondary bacterial infections for the 3rd time now, over a span of a year, roughly. The infections have nothing to do with water quality, I always test before and after water changes, and I never let nitrates exceed 20, at the most. I've never had any other sick Discus, no other has had this problem. It's the same process each time, separate him, treat him, get him back to strength, put him back for an average of 4 months. I'm just worried one of these times it's going to be too overwhelming and he's not going to make it, he's my favorite and my first ever Discus and my heart would be broken if he passed. I was just curious and what I should do, separate the pair into a separate tank was my first thought, but I don't really want to separate him from my display tank, I want to give him a quality life. The only other solution would be to add more LOS blocks in the tank, considering I only have one in the middle and that's where he lays, every time, and that's where all the Discus go to sleep and hide so it effects everyone else as well. If I added an additional two on each side of the tank, do you think that would be a viable solution so everyone wouldn't feel like they have to fight for a spot to hide, there could be other places to run off to, or maybe propose a different solution? Help and advise is very appreciated, thanks lots in advance!
