OK, I am thinking four things on why my bala shark has been loosing his color, please tell me what you think.
1. Not a complete diet, (need some veggies)
2. pH too high or parameters incorrect. (actually my pH is a little high)
3. Too much stress from being chased by the black shark, and not being in a school.
4. Too much light, my light is not very powerful, actually a bit weak, but the balas don't use any of the shady spots because they don't fit or are occupied by the black shark and or pleco.
Dosn't have anything to do with the subject but:
I noticed my black shark likes to rest in the nooks of this big plastic root decoration. I am not very worried because he is probably taking a rest since the current is fairly fast in my tank, or it is just a trait of his own, or all black sharks. What do you think about this?
