Advise plz..

I have a 60 gal tank..I have a lion fish, Dogface puffer, Green wolf eel & a yellow tang. The other day I left the house for only a couple hrs came home and found my Yellow tang laying on his side breathing very fast with my lion fish hoovering over him?..took tang to pet store they said the tang might have aggervated the lion fish, & lion fish stung him..okay.. next day trader the lion fish in figuring that was the problem..& got a sailfin tang & Niger trigger ,inplace.I've been reading on the internet about tangs..& now im worried it was my oxygen level..not for sure..I've been watching my Niger T., he seems to be breathing a lil heavy, not a lot though..not sure if he suppose to do that or not?? so i added more ripple to surrface just in case..ANY ADVISE???

 

you should always try to have surface agitation. did you test your water?
how old is the tank?

 

What are your water parameters? You should also try to always figure out the problem of a fish's injury before replacing any fish with new ones. Breathing heavily is a sign of low oxygen levels, but it could be something else too. Oh and yes, you should add some more agitation to the water, that will help.

Edit: Your tank is over stocked too BTW. Should be about 1" fish per 2g. Welcome to 3reef.

 

The tank is about 4 months old..

you can start by telling us your water parameters.

do you have a nitrate test and hydrometer?

 

I'm sorry to hear about your loss. +1 on agitation. we need some water parameters.
