Scientists are unsure if chicken, fish and seafood could have problems with prions. Roger Morris from MRC Center for neurobiology is doing research to see if mutations could cause this problem.
You can probably add gobies and/or tangs depending on the size of your tank, but remember that clownfish are territorial and having more than 1 or 2 could cause problems
