I am a fish breeder or trying to be anyway. I hate euthanizing with clove oil and I would much rather feed the otherwise un sick but deformed fish that need to be euthanized to this frog. I can reasonably say around a guppy will be the largest that will be fed and I will always try to get them smaller when possible. My first question is how large of a fish do you think a male could eat safely? What size fish for a female max? There is a chance I might be picking up some this weekend one for 10 gallon tank. the only issue is they are about an inch the lady on the phone said. so is there any way that I could cloaca sex them or should I just get the largest one they have. I have not set eyes on them yet so I'm not 100%. No other animal will be kept with this animal that is not meant to be eaten. and I will make sure they eat some good mealworms possibly some fruit flies while they're little and some good quality fish food I'm talking Xtreme quality. I do not want the animal being eaten to suffer more than it has to and I want the frog to be able to thrive. I already have two toads and a mantis this frog is not only wanted for this but as another beautiful baby. Sorry this was so long any advice would be amazing.
