So a few days ago at school a girl brought in two turtles. She was going to have them live in her locker D: but then decided to but them in one of the teachers fish tanks (about 20 gal) and the tank has three goldfish in it each about 3 inches long. Also so people could tell them apart she painted pink designs on their shells. Is this ok? Because I dont want either the fish or the turtles being harmed from this.
They are probably red ear sliders. No not okay. They need land, heat, UVB lighting, good greens and bugs, and they can get to be gigantic. They are basically pond turtles. And the paint isn't good long term.
Look up red ear slider care, I am on my phone or I would type mote
Turtles cause even more of a bioload than goldfish. They need an insane amount of filtration because they make a ton of waste. I can't imagine the goldfish enjoying that. The turtles also need heat or they will die, and the goldfish won't like that much either.
I know for the regular sliders, 125 gallons is need for a female, 75 gallons for a male. Basically you take the full size of the turtle and x6 to get how long its tank should be. Probably the same for that type of turtle.
