Sweetheart parrot fish

Question
I bought 4 sweetheart Parrots, I bought them before I read on this site that they are injected which is awful.
but I don't know much about them, my qustion is this, they sometimes break out with black spots all over its almost like when they get a little stressed this happens, is this normal? if not what could it be? it doesn't look like ick.

Answer
Hi There,
Black spots are usually scabs over areas that are healing. Your fish could have scraped itself on something sharp in the tank, or if you have a new tank, it may be recovering from ammonia burns or some other water quality problem during cycling.

Rarely, the black spot could be a disease passed on by snails if the snail has been exposed to bird droppings (as in an outside pond) and is still in the first generation.

I recommend daily water changes to improve water quality as this sounds like the problem.

Hope this helps,
Chloe :)
