It dose not matter what age they have to be to eat earth worms
our red slider turtle is 1 1/2 years old and she will eat 5 small goldfish at a time.
Its really a gamble to put any fish with a red eared slider , it depends how big the sucker fish is if it is small the turtle with probably eat it , you are supposed to let them grow up together i have a sucker fish with my red eared slider but they are baby's so they have not bothered it.
if the red eared slider's shell is 15cm. it is 5 years old!
Red Eared sliders are aggressive over food, territory mates, etc. Most likely it was due to that aggression. I would suggest separating the sliders and taking the injured slider a vet. Good Luck!
of course! i have a baby red eared slider living with a big 8 inch turtle and they get along! you have to make sure they know and like each other before you put them both in the same tank
let them hear it as it drops in to the cage.
Same as any other animal, either old age or some kind of disease.
Yes. The most common fish a Red Eared Slider will eat is Commet Goldfish. Red eared sliders will eat fish, but fish are full of worms and parasites which will contaminate your filter. For an indoor slider I suggest only pellets and veggies. Plus they eat parts of the fish and the rest you would have to clean out right away. My slider loves just his pellets, he snubs romaine lettuce and any other veggie I have tried. Ice berg lettuce is not good for sliders either. I have a 4 year old slider that is 5 inches long he is in a 40 gallon tank alone.
A commercial diet such as Reptomin Turtle Pellets. A good supplement is Turtle Bites, which are made of fruits and vegetables. It will also eat red leaf lettuce, which can be given daily. Other fruits and vegetables can be offered but should be limited to once a week.
feed it turtle food but make sure the food is big.feed it lettuce and krill.also earthworms and fresh fish.
It probably isn't normal, and it does not sound normal I would probably think about consulting a vet.
