hmmm..
well still a noob but, chucking in my 2 penneth,
i have adf`s with all my fish, they certainly dont go without food, and nothing, and i mean nothing messes with the frogs. they climb over fish, rest wherever they want and as for feeding, well, bloodworm is unreal, all of them get their fill and some, iv`e watched a frog stuffing his face quite happily and a male krib joined in next to him, the frog head butted the krib out of his space and carried on eating, all the fish sort of stop swimming and divert round the frogs, it looks like, what the hells that? then move on, amusing to watch.
might be just lucky i dont know, but thought id let you know
cheers
