Ok, new update. I think the biggest source of my problems/stress with these fish (besides the one not eating) comes from trying to listen to everyone's opinions. I've been in this hobby long enough to know that everyone has a different way of doing things and there really is no right or wrong way, just what works and what doesn't. That being said, I've decided to try to stick to one person's advice that person being the lfs store owner I got the fish from, he's very knowledgeable on discus and breeds them as well. What he told me today is pretty well on par with what the majority of people have said (stupid me, went with the minority when starting this tank). I had 2 people tell me to go the planted route, stupid me, should have known better, I've never done plants before so doing a discus/planted tank to start off with was a bad idea. Most people said barebottom with no decor was the best way to raise baby discus (including the lfs owner), stupid me, I put in sand and plants.
So, I went to the store today to bring back the not eating one, and swap him and when I got home I pulled out all the plants and got out some of the sand (I think it will take a few w/c to get it all out). It's funny but now with all the plants gone, the discus are all over the place and not hiding at all. He also said (as did another discus expert in my area) it is better to keep them a bit overstocked in barebottom tanks, becuase more fish means less aggression and of course barebottom is easier to clean. So I now have 7 discus with no plants in what is soon to be a barebottome tank (at least until they are adults) and they are swimming all over the place! I should have never let myself get talked into doing plants in the first place! Oh well, I guess that's the thing about the hobby, it would get pretty boring if there was nothing new to learn. Now I just hope everyone behaves themselves and eats!
Also, I'm just wondering what brands of flake/pellets you guys feed your discus? I would like them to eat a good variety.
Thanks so much for the help guys! I appreciate it and will keep you posted.
