Food for Kassinas?

[Kurt]

I've tried defrosted bloodworms by hand, but again, no interest.

Most frogs will not eat any thing that is not moving. I watch my frogs all the time, I see them tracking prey all the time. If the prey stops moving, the frog will lose interest and move on. Its like the prey all of a sudden became invisible when it ceased to move.

Should they be eating a more varied diet? What should I try? Would mealworms be a good choice? Would you put mealworms in a dish to stop them crawling round the tank? I know with axolotls mealworms need to have their head crushed before feeding to the axie, is it the same with frogs? I don't think my two will eat anything that's not moving, they seem to hunt by movement alone.

Mealworms are high in calories, but sadly the are high in chitin as well. Too much chitin in a frogs diet can cause gastrointestinal impaction. Also you don't need to crush the mealworms when feeding them to a frog. So feed them sparingly.

Also should the crickets be dusted with calcium? As I don't hand feed the frogs, I don't know how much calcium they would actually get as the crickets can live in the tank for a few days before getting eaten.

Yes, dust the crickets with calcium, as well as vitamins A & D3. If you feed less crickets at a time, that will assure that the dustings are less likely to go to waste.

Sorry for so many questions, there's not much info out there with regard looking after Kassinas.

Its OK, thats what we are here for.
