Hey, I haven't been on this forum for years but I have still have discus but have scaled down and have only one tank of discus. Recently I have been buying dwarf rams for the discus tank and surprisingly they die after a couple of weeks or so. They tend to get darker in colour and once I notice this they are usually dead the same day or the next. The water is kept at 31oC and pH about 7.1 The tank is 5 ft with 7 discus and a couple of rummy nose tetras which are all over a year old or so with no problems at all. I do weekly water changes about 1/3rd of the tank. Water pretty soft (use resin) and nitrates should be pretty low although I have given up measuring all these things. Their diet is predominantly NLS discus food and beef heart 3-4 times a week. Surely these guys are not too hard to keep? I was thinking that if i can keep and breed discus, tropheus and frontosas any other fish should be easy as.
