1green chromis MIA
1green chromis dead
as of now live stock are...
vagabond butterfly
2 clowns
2 firegoby
1green chromis
the last chromis is not looking that great either....
45g + LR
Amonia=0
ph=8.2-8.4
so heres the thing, i have never dealt with fin rot before...and the dead chromis had the same bahavior hiding before it died.
will this spread to my other fish?

Is it fin rot, as in raggedy frayed fins that look like the torn bottoms of old jeans, or are the fins chewed, with notable chunks actually bitten off due to aggression from another fish? Can you post a picture?

ill try to get a picture, but the fin (pectorial) is hard enough to see in person, he's got some fraying of the back fin im sure i can get a pic of that...if he comes out of hiding.
thanks Beth!
also: does fin rot spread? & why the hiding?

Think of "fraying" as ragged fins such as in old clothes that have the threads coming apart....that would be an indication of poor health and possibly a bacterial infection.

ok,
I lured him out with my homemade seafood/garlic mixture.
It appears that hes healing, BUT i have identifyed the source of the probelm.
The new fire goby is harrassing the established goby.
At first they schooled and were buds, now appears there is territorial disputes....
I am going to move my LR around to see if i can get some peace.
suggestions?
