I have a LOT of photos, as I know you all like to see pics to determine what is going on. Please help me. If it is pyramiding, can it be changed? Like if I change something about his feeding habits etc will he be able to grow into a non-pyramided shell?
Also, what are the white marks around the old scutes? It looks scraped or something, I hope it's not shell rot is it?!
Some info:
He is a yellow belly slider, I got him as a hatchling in August (6 months ago) he and my other turtle are kept in a Juwel Rio 180 (55 gallon) tank.
They are fed Hikari Turtle Sticks and Vita Terra Turtle Pellets. I used to feed them a small handful of pellets every day (maybe about 5 pellets each), now I've started feeding every 2nd day. I hand feed them to be sure I know how much each is getting and to prevent aggression.
They also have feeder fish (neon tetra's, 2 female bettas and guppies) in their tank, plus a steady supply of anacharis and cuttlebone. Those 3 things they have 100% of the time.
They have an above tank basking area with UVB / Heat lights and their tank is filled to the top and kept very clean.
He shows no sign of any illness or anything, he swims a lot, eats, basks etc
Please tell me if there is something wrong with him and what I can do to fix it if there is... I'll do anything.
Here are the photos I took today:
