i thought you were going to use paper towels, in which case you dont need a water dish. if you already have a water bowl you can put it in there, it wont hurt anything. zoomed makes these little yellow feeding tongs. i dont feed guppies, i would feed small goldfish or rosey reds. i just grab the middle of the fish with the tongs and then either drop it in front of him and as it wiggles it will trigger him to go for it, or if he doesnt i pick it up again and rub it along his mouth which triggers him to bite it at which point he realizes, this is good, and eats it. the best thing for fish is to have a small tank(2.5 gallon) to keep them in and feed as needed. feed the fish well because most pet stores dont feed them well, if at all. they usually only take live, and im not sure how nutritional those freeze dried things are. use the tongs whenever you need to do something around him, because if he bites them, no big deal, if he bites you or your kids people usually jerk back real quick which can hurt the frog. if bitten keep your hand still and let him try to eat it, he will realize he cant and then release you . this may take a few minutes, but just sit and wait. you may be able to speed this along by rubbing his nose with the flat part of your fingernail, not the tip. putting them under water or running hot or cold water over them will get them to release as well, but this is more stressful for the frog than letting him figure out he cant eat you. it hurts a little, but isnt too bad. once he releases wash your hands really well, preferably with an alcohol based disinfectant. there is a reptile water-less hand sanitizer called 'wipe out 3' that is good to use after every time you handle him or his cage, or if he bites. when i handle mine i get my hands wet with her water, from behind her if if i can, if i cant than i get it from far ahead of her, too far for her to try and bite me from, and then i come from straight above so she knows its not food and cant bite me. then i just pick her up. avoid fingers touching him around his mouth, as this may prompt him to try and bite them. for his size, go ahead and measure him with a ruler if you can. i have had nickel sized pacmans take pinkies, which are about an inch long, without problems. but i would not recommend it since it really is pushing it. just have your kids set the pinky in front of the frog with the tongs, or if he doesnt take it, have them rub the pinkies head on the frogs mouth using the tongs, same as the fish. you or your husband should watch, at least the first few times, to make sure the kids arent sticking their fingers in there, teach them what to do if they ever do get bitten. unless your kids are teenagers they should not ever handle him, either you or your husband needs to pick him up so the kids can clean the cage. even teenagers should be shown how to do it right. remember to re-enforce that everyone needs to disinfect their hands before and after handling the frog. this ensures you dont get him sick from whatever you were doing before you handled him, and you dont get sick from handling him.
