So I decided to try out some discus since my LFS had them on a buy 2 get one free. Had the water parameters right, ph was a little high but I acclimated them to it slowly. First few days, they were doing very well, then I got home one day and found one dead. Ok, so the freebie is gone. Bummer they won't take it back cause its beyond thier return policy. O well. 2 more days go by and find another one dead. Got one left now and so far its been doing great by itself. So I have a few other severums to trade in and go to another LFS and see 5 red koi angelfish in a tank. Worked a deal with the owner to give him the severums and take the 5 angels for 60 bucks. Get them home, and put them in the tank, first few days they are doing great, then I see one hanging at the surface with clamped fins, quarantined, dies a day later, then every day after that, one after the other they all die except one. Now I have one angelfish and one discus in my 75 and am worried about even spending more money on either.
