So, I've made some major changes lately. I recently purchased several anubias, tied them to some driftwood, and I also dropped a few water lettuce into the tank. I've also started using Flourish Excel. That was about a week ago, and I already see a difference in all my plants. And I've also adjusted my water change schedule - 25% every other day now, no exceptions. My nitrates are down to about 10 ppm now. And the remaining algae in my tank is all but gone! Happy happy joy joy!
I brought my last angel back to the fish store, and picked up 3 more discus, bringing my discus total up to 5. Using a dripline to adjust them, they were happy and out exploring the tank within a half hour! No darkness and hiding in the corners, they were basically happy right out of the gate. But here is where things got hairy. The two discus that I already had (Peri is one of them, there's a picture of him earlier in this thread from back when the tank was still a disaster) they became ultra aggressive after about an hour. I mean, they were both totally viciously all out chasing and attacking the 3 new guys, to the point where the new guys eventually were all bullied into a corner behind a rock, and they wouldn't come back out.
Now I've read that this is kinda' normal if you don't start off right away with a pack of 6 or more all at once. But what to do? I don't have a second tank to give my aggressive discus a time out. What I came up with is working well at the moment. I am using two large nets, with a small stone at the bottom of each to pull the net down in to an inverted pyramid, resting on top of the tank so that they hang down into the water. I captured and placed each of the aggressive discus in their own netted area. They can move around a tiny bit, and they can't hurt themselves or the newcomers now, and the newcomers are perfectly happy once again. Whew! Obviously I'll have to let them out eventually, but I think I'll keep it this way for another day, and hopefully when I set the two aggressive discus free, they will feel like the newcomers and try to join in the newcomer pack. Sounds iffy to me, but that's all I got for now.
I hope this works, because if it does, I will FINALLY have a tank I can be proud of. If not, well dammit I'm at the end of my rope, and I think I'll just let them all try to kill each other, and to hell with discus.
