I have a 125 g tank that has been set up for about three years. 70 lbs of live rock, power compacts. Some leathers, mushrooms ( several types) in it.
Currently have a yellow tang, flame angel, clown, blue "hippo" tang, and a recently added Naso tank (3 1/2 wks ago).
Lost a sm. flame cardinal about 2 months ago when I was on vacation. Disappeared.
Naso tang got ich when I added him and wouldn't eat but added Kich Ich and it cleared. Ran out of Kich Ich and it reoccured till I got to pet store to continue treatment. When it reoccured hippo was now showing signs along w Naso (mild). Started treating w Kick Ich about a week ago and everything was still eating strong. Skimmer is off. Recent water change was done and all levels are good. ( when I started adding new dose of Kich Ich)
Came home from work today, and hippo is sitting at bottom of w mouth open but looking better as far as spots. I feed the fish and he swims to the food but can't seem to close his jaw. He was excited to see the food but wasn't eating, it seems like he can't close his mouth. Any suggestions on treatment or what it is?
Local pet store wasn't sure and suggested maracyn or maracyn II????
I appreciate any help
Lock Jaw on my tang! What is it?
