Last night along with the introduction of 5 small Chromis, I did a 25% water change (30 gallons of a 120g tank). Today Blue Dot Jawfish who I've had about a month was seemed in distress. When I got up this morning he was out of his cave and he'd lost some of his color. I fed the tank some mysis (something he's always eaten heartily) and he refused to eat ? he?s never refused to eat.
I watched him for a bit and while he eventually went back into his cave, he kept going in and out every minute or two. He didn?t go anywhere, just came out, turned around and went right back in. At one point I noticed a bristle worm stuck to his tail, something he usually sees as a snack, so I was surprised. After some effort he was able to shake it off and went back into his cave again.
This evening I fed the tank and again he refused to eat. I put some more rubble around the opening to his cave and after a few minutes he moved a couple pieces and that was it.
There are a few factors that may be playing into this. The first is the little school of Chromis like to hang out near his front door and will dart in the back door if frightened. They also could have brought some parasite in with them I guess, but I thought it would take longer to manifest. Secondly, tonight was setting up my Bio Cube and calibrated my refractometer with RO water. If RO gives an accurate 0 reading for calibration, my refractometer was reading high by .005 (so reading 1.025 but really the salinity was 1.020). It had been quite some time since the last calibration so it's been like that for a while I suspect and this Jawfish has been through several water changes with it like that.
So, does anybody have any idea what could be going on with my Jawfish? Also, do any of the vendors here have salinity calibration fluid in stock or can I borrow some from somebody so I can know for certain if my meter is accurate?
Since it's late I'm and may be a while before I get any responses, in case it?s a parasite I'm going to fire up the UV and hope it doesn't nuke my pod population and starve my mandarin.
