Thanks for the quick responses. I went to my LFS
, couldn't find anything with garlic. However I went to the store and got garlic powder. I mixed some water with the garlic powder (probably like a 90/10 water to powder ratio, so not a lot but enough where the krill smelled like garlic when I took them out), let some thawed krill sit in it for about 15 min, then spent 30 min trying to get him to eat with no luck. Right when I put the krill in the fish tank for the first time he comes over curiously but just kind of sniffs it and then swims away. The only way I can get him to put it in his mouth is if I literally touch it to his mouth and then he will grab it, but spit it out soon after. So unfortunately the garlic doesn't seem to have changed anything. However, my trigger was happy to eat it after my puffer turned it down!
I am running out of ideas with the puffer. In addition to trying the garlic, I got 2 live clams from the store yesterday. One went to the trigger and eel (which they loved) and the other went to the puffer. The puffer acts like it isn't even in his tank, and it's been roughly 24 hours. I am hoping he will get curious and try to get into it in the next day or so. There has also been a snail in there with him for about 3 days now which he hasn't touched either.
I also bought a couple mussels in the hopes he has more of an appetite for them. But as of yet they are not in any tank.
If you guys have any other ideas I would love to hear them.
A side note: He did have a very minor case of ich when I purchased him and I treated him for it. The ich is almost gone. I am assuming this might have a negative effect on his appetite?
