Yes, he does look better there. What about hiding spots in the QT??
I'm going to suggest offering this clown some fresh seafoods. You can add zoecon to the mix, or, if you can get beta glucan from your health food store, you can try that. You can get a bag of frozen seafood which are sold to make seafood salads, oriental foods, etc., at the grocery store [ask the attendant at the seafood counter] or you can see what is available that he can put together for you right at the seafood counter. Stuff like: octopus, scallops, shrimp, squid, clams, etc. No oily fish. [Though, if you have a fish with HLLE, you may try some direct feeding of salmon.] Food process this mix until it is pretty much a "mush" then roll it out on a flat pan in a square shape. Freeze it until it is solid, but not frozen like a block. Depending on how much seafood you got, you may be able to cut this up in a few 4" sq blocks [the size that brine shrimp in pkged in--the non-cube variety]. Do the cutting then place each "block" into a small freezer ziplock for storage [each having their own bag]. You can cut off chunks as needed for feeding. Believe me clowns love this mix and it is very nutritious. If you can get the zoecon or the beta glucan then add some directly into the seafood as you food process. If you are also feeding your fish veggies, like seaweed selects, you can, as well, mix this right into the food processor with the sea food.
As far as I'm concerned home made foods made specific for your type of fish is the way to go, particularly fish that are obviously not healthy. It is easy and cheaper than the watered down foods that are sold for the hobby. Look at the ingredients of any frozen foods sold for the hobby. What is the primary ingredient----?
