UPDATE: A lot of are adults have been having problems. It seems its all about bacterial infection. This has killed 3 pairs of angels and deformed some fry (fins bending fin rot ext,) This started about a month ago and we have been treating with a few kinds of meds. Buy none seems to effect there health. I (Nick) am thinking its the food that is doing this. This started about 2 weeks after we switched from angels plus food to omega-one color flake. Could the food be causing this problem because are water is perfect and each tank has its own sponge filter and none are attached to other tanks. Despite are water being great we have done daily 50% water changes and this with the meds does not seem to be improving there health. If it isn't the food and the water is great then I am truly stumped. We use ro water with ro right and tap water with prime for water changes. The frys look fine with the exception of some bending fins\fin rot. The adult\juv angels them-self are at the top of the water in some tanks at the bottom in others some have red\pink gill plates and others look perfectly normal. They all eat the omegaone color flakes. Also as a side note this seems to only be effecting angels i have rams in the same tanks and they are just fine.
