Small crickets can be added here as a side dish. Frozen bloodworms , brine shrimps , water fleas, white shrimps and 'Tropical Tucker ' are fish irresistables. Bigger fare for bigger tummies Larger mealworms and waxworms for larger birds, any sized turtles and tortoises, monkeys, bats, rats, mice, ferrets, hedgehogs and so on. Locusts grow to 50 mm so the variety of sizes available makes them particularly versatile insects. Feed to larger reptiles, amphibians, birds and mammals.
Crickets are a little smaller as adults but no less versatile.
The 'top shelf' in terms of nutrition, however, is the waxworm.
