We have feed "tabis" to our Hypan's which at the time we even recommended it to a friend, also with Hypans because they loved it!!!! However if you look at a post I made some time ago in regards to bloated catfish and then we both had unexpainable deaths due to bloat. We made some inquiries to a well knowen owner of a fish shop and he made some inquiries. JBL came back and said under no circumstances should Tabis be feed to Hypans (go figure there is a l046 on the cover of the bottle!!!) Too late for us now as we can not recover the fish that we lost, my advise to any Hypan owners is stay well away from this product
p.s we feed this product to other non Hypan Plec's and they love it!! and they are deisgned too
