Only Mloto Fireline and Likoma are dying?
So I'm not new to the Hobby but this one has me stumped. I have lost three fish (in two different tanks) in a six day time frame, one every two days. The interesting part is that they are Mloto Fireline and Mloto Likoma that are dying off. Here are the facts: Tank sizes 65 and 120 established, UV sterilizers in both tanks, peacock and hap tanks, food Extreme cichlid flakes and pellets no junk food, water quality 0 ammonia 0 nitrites 20 and 25 for nitrates, pH 8.2, Temperature 80, no warning signs prior to die off, no visible signs of illness fins and scales are perfect, eating and swimming normal, no bloating, Fish came from the same breeder in Florida two months ago, No new fish have been added all other tank mates seem fine. Iím trying to figure out if there is something species specific that is the cause for the die off. Does anybody have any thoughts on the matter.
