I am on fish duty this weekend as Bev is away. How much are you meant to feed fish? We have 7 Gourami, 6 Rasbora, 5 Rummy nose tetra, 6 Glass cats and 2 BN. They seem so hungry but how would I know if they are tricking me and they are not hungry? Also - I stuck some algee wafers in for the BN and someone else ate them. Who out of that lot would be keen on them as well. I know it wasn't the BN bros as they were not interested whe I put them in. Not even ten minutes later they were gone. Tonight I fed them a cube of Brine shrimp and a pinch of flakes... is this enough?
