lots of small tetra, some danio, gourami's, ram cichlids, guppys, a loach,yes its a high protien food and if you do decide to use it then remember that they make a discus varrient witch i suspect has a higher protien content although i am not certain i will post the contents list and other values tommorow if i remeber what fish do you plan to feed it to?
the protien content for the discus version is 47.5% oil 6.5% fibre 2% ash 10% moisture 6% and added vitamis
im just confused as to why there is ash in it and not a higher vegetable content
