Hi, I have a 55 gallon mbuna tank. I origanally started off with too little fish and some died due to an aggression problem, I recently added ALOT of new fish to counter the problem (20 some new fish added to the original 7) I got them from a friend at the University of Maryland. some of the species were very exotic like the Metraclima Mustardi, any how, after about a week a fish would become reclusive and die the next day or maybe two days after. this happed about every week for some time (Like 5 weeks) I passed it off as "survival of the fittest" but now it's starting to scare me as my Mustardi is sick
I realize im probably going to loose him
but he was deffinately one of the more dominant males in the tank. Yesterday I found him sitting in a cave at feeding time (very unusual for him) and today I found him upside down on the bottom of the tank with almost no color.
he is still alive. I thought it was bloat, but i didn't notice any stringy feces or bloated stomach, he just looks well, dead
hes not even breathing fast. My water quality is exelent with a little bit of nitrate, the water is crystal clear, NO JOKE!!! im dumfouned any help would be appreciated. I also ruled out parysite because his stomach isn't shrunken either.
