hi i've recently bought a 95l fish tank, i went to buy some fish the other day ended up with 2 neon jewel cichlids 2 crabs and a plecostomus.. anyways been feeding my fish with just normal flake food and they seem to be eating it all and not leaving much for the crabs.. i think pleco's don't eat flake food as i've read on the internet, anyways was wondering wether i should put 2 algae tablets in at night for the crabs and the pleco, the plecos about 3.5" long and the crabs are only small, not sure the amount of food they need plus my tank is very new so there isn't much algae growing on anything for the pleco to eat, if anyone could get back as soon as possible that would be great, thank you !
