Hi i'm new to the forum and I have an urgent question to ask!
So I got a new 7 month old male 3-striped mud five days ago, and he hasn't really moved much since I got him. He's either in my sloped beach like side of my tank, or he's chilling in my fake plants near the surface. He also ignores the food I put inside, maybe he's just adjusting? But him not moving much is worrying me.
It's a 55g tank that has housed a painted turtle in the past, only about 8" of water but has tons of places for him to climb, plants, driftwood, etc. water temps are around 78-80 degrees, and basking area is around 88-90. I think it may be my filter output as it's actually pretty strong but only on the surface, I have a rena xp3 that I got secondhand and apparently the person before me rigged the motor a little so the output is pretty high. The 6 black skirt tetra in the tank don't mind the current as it's just the surface. Could it be the current that's keeping my turtle from exploring? Or is he still adjusting?
I have plans to introduce a female 3-stripe mud this Saturday around the same age as my male, I was planning on this before I even got the first little guy so it has nothing to do with him not settling in well. do you think adding her would do more harm than good? Or will it not matter much.
Any help is greatly appreciated! I'm getting pretty worried.
