Hello,
I brought home a new baby red eared slider turtle into my 75 gallon fish tank that has four tin foil barbs and a few other small fish, around 5 days ago. I created a basking platform too.
On day 1, i tried feeding him tubifex what i use for my fish. He just ignored it. I took him out of the tank the next day into a small turtle bowl and put small gratings of carrot which he ignored again. I got tensed because of this behavior. I consulted a few online forums like this one. Everyone of them suggested the tank size, temperature parameters and i am adhering to them. I asked a friend who owns two healthy baby red eared sliders for some help and he suggested i brought home a companion for the baby turtle to coax it to become more active. I conceded and three days ago, i brought home another red eared slider exactly the same size from the same store. The new one enticed the older turtle to swim about in the tank and i was getting a bit more positive about their condition. However, they did not come out to fetch the fish food from the surface. They used to bask all the time. This is when i decided to introduce some live food, hence got some earthwoms home. I took the turtles out into the bowl and placed the earthworm. They both seemed to swim around as usual without bothering the earthworm. My friend's turtles however readily gorged up the worms. They are of the same size, probably a month older.
What should i do?
I took the turtles out to sunlight, they are active.. but not eating
Please help. 
but for their sake, i will]
