i have 3 turtles too......
from 50 cents coin
now become like one big piece of rock hahahhaa
their diet consist of kangkung and cabbage
i dont feed them pellet anymore because it makes them grow even more like a monster hahaaha
there are more than 15 years already
i cannot tell which is male or female but some people said turn your turtle and you can see from the pattern mark..
they spend most of their time stacking up one of each other..
at times they love to swim..
at times i just leave them at the porch for roaming...but they dont end up together..one north, south / east or west...
my turtle eats kind of lot.
the moment the lights are on 630pm
the whole container will start rocking and they make sound asking me WHERE IS MY FOOD?????
after eating - then everything turn into silent....
i need to wash the swimming pool everyday because its very dirty with their shit hahahaa
their shits are good for fertilizer for plants
no wonder the flowers and leaves all fat fat....
thanks to my turtle murky green shits hahaha
