Hi maklouf,
White bait, blood worms and worms are not good foods for turtles. I know that your turtle will eat these foods, but that does not make them suitable or nutritious for a turtle.
Freshwater turtles eat underwater. Therefore, anything that lives in freshwater is potential turtle food. Try switching to foods such as freshwater fish, freshwater yabbies, freshwater prawns, freshwater snails and tadpoles.
How long have you had the turtle?
Was he wild caught or captive bred?
When he floats, is he:
a) level in the water;
b) leaning to one side;
c) floating with his rear higher?
Are his legs and neck extended or tucked in when he floats?
