i surely hope not, i just spent like $400 on fish food from the statesThey would be just spirulina wafers which are great for bristlenoses and maybe even the panaques will eat it. Good luck getting any of the other plecos to eat it though.
Hikari has a pretty high ammount of more meatier ingredients in its algae wafer recipe.
If buying off ebay, make sure its in Australia. Aqis quaranteen will confiscate any fish foods coming into Australia if you don't have an importers permit.
