The trouble is, if he has ready all the care sheets, and most seem to say more or less the same things regarding diet for instance, and is still wanting opinions and everyone will have a different opinion, he's going to be just as confused as before. It would have been simpler to ask specifics like for example, I have ready that I should feed X or Y, do other keepers feed these? Just reading up, and then still wanting opinions will leave him more confused than before.
Before I got Winston, I ready up on the basics, thought about what was absolutely essential and how I could set things up to provide the essentials like water either with chemicals to 'condition it, or taken from my many fish tanks, space, suitable substrate, and diet . And Winston being a bullfrog means he'll eat just about anything which moves. In Summer he gets big fat juicy worms from my land because they are free and save me money, Lobster roaches which I breed for the other amphibs and reptiles and are free, large locusts which I have to pay for but which he enjoys hunting for and the occasional small mouse , which again I breed and cull for my other animals.They aren't complicated to keep I don't think, and the basics are covered and repeated on just about all the care sheets, so if he has done his research, he should at least have enough knowledge on the basics and simply asking for yet more info will muddy the water and make him even more confused.
