Firefish just one day decided to not show up for the whole day. This was maybe 5 days ago. Did a water change but nothing new. I can see him where he is hiding and I took away the rock where he was hiding and he just sat there for a bit then swam into another hole.
I have no other fish mates in the 20 gallon tank. Only inhabitants are peppermint shrimp and cleaner shrimp. Also the normal hermit crabs.
I will test water tomorrow but it looks like the peppermint shrimp and cleaner shrimp are completely healthy.
I'm scared.. I had 2 clowns die of ich because of the absence of a quarantine tank... Now a firefish that will refuse to come out. It has no visible ailments that I can see. No white spots at all. I left the tank fishless for 2 months before I added this firefish.
Here's the cute little bugger.
Please help me save him! I will test water tomorrow!
Edit: And I also tried offering him food. Usually he goes up to the surface to eat the stuff there before it sinks. He of course also eats the sinking stuff. I also put food in his hole but he didn't even take a bite from what I could see... I've never had him hiding in his hole for that long. He usually only hid when he got startled. Otherwise he was out and about!
thanks!!!
