3rd fish to die in two months , need help

[Samantha_p]

as I said before I have a not so common community tank.
my 125gal tank has 5 goldies,5 angels,2 common plecos,1
severum and the latest addition a baby red blood parot. well
about 2 months ago my 6"comet was floatind dead, 3 weeks ago
one angel was also floating dead. know,today after work I found
my black moor Goldie floating lifeless. I feed them once a day,and
do my pwc every other week, I got 2 Rena canisters and a big sponge filter. I got a searchen in water amonia monitor and also a searchen ph monitor.
my amonia levels are always showing safe and my ph is always
about 6.2. i've had this set up for over a year,it's when I introduced
the blood parot that my fish started dying. can the blood parot be the
cause or is it just a coincidence. he looks very peace full during the day
but who knows how his like at night. all the advice you can give me
is appreciated...thanx

It's very possible that your new addition had some sort of bacteria that he transfered to the rest of the fish. I would try to qt him in another tank if possible and do a serious water change in the main tank.

What do you mean the ammonia levels are normal? 0 is normal, nothing else.

i think i suggested this in your other thread. i have no doubt its the blood parrot. theyre not a community fish, and theyre pretty aggressive. I say rehome it or set up another tank for it and compatable tankmates
