So I recently got a trio of pajama cardinals from Divers Den(which came the highest recommended through this community) and I set up my QT for them. I do a 25% water change every other day while I dose with Seachem stability and prime to make sure they arent being harmed by ammonia. Water temp stays from 78-79, and salinity is about 38. Everything seems fine, water stays clear and clean, and on water changes I also vacuum the bottom of the tank to remove as much food waste and fish waste as possible. I have an air stone in the tank, as well as a power head aimed semi at the surface, and the fish dont seem to be disturbed by it. My only concern is I havent seen them eat yet. They arent swimming weird, they are acting just like you would expect cardinals to act (from what I have seen on videos and at my LFS). These are my first cardinals so I dont have much personal knowledge to rely on. I have tried feeding them multiple different foods, (chromo boost, formula 1 and 2, frozen mysis shrimp, brine shrimp, etc) all of which are within their diet, however I just dont see them eat. They dont look sick, they dont look too thin, all signs honestly point to them being fine, I am just concerned that I havent seen them eat. I dont know if cardinals will eat off the floor like my tang will if they dont get the food as it drops. They have been in the QT for about 9 days so far, and I havent seen them eat a thing. I know sometimes with shipping and new environments they can be stressed and not eat, so I didnt even try to feed them for a full 24 hours after they went in the tank, but now more than a week later I was hoping to find some more information. They mostly sit around the bottom 3-4 inches of the tank, so they dont see the food falling. Will they find it on the floor and eat it, or should I be worrying about this?
