Does anyone have knowledge on Bala Sharks? I have a horrible habit of killing them 
I have them in a 30 gallon tank with mainly Cichlids. (2 Parrot fish, 4 Serpae Tetra, 2 Blue Acara and my lone Bala Shark, there used to be 3)
My water tests are all pretty good, my Nitrates are at about 80ppm and my pH is around 7.4 - 7.6. My Ammonia and Nitrites are 0.
Any help is greatly appreciated!
