Hello! I've been somewhat obsessively stalking this forum for some time since I acquired two baby red eared sliders to get started, but I'm posting now because I'm starting to get a little worried for them.
I "rescued" them from my own family, who got them (likely illegally) from Chinatown as hatchlings to please my much younger brother and sister (4 and 9 yrs old). I have them in a little setup with me in college right now, and got them a tank, a heating lamp and UVB bulb, a floating dock, a filter, and a water heater, with some plastic plants and decorative rocks (which are large, so they don't choke on them). I'm currently looking into getting them a much larger tank, but since I'm a college student, I have a very, very tight budget--I've been scouring Craigslist for some used tanks. The other problem with having very little money is that I can't really afford to go to the vet unless I have no choice, which is not great but at least better than them dying at home.
The turtles have grown a little since I took them in two months ago (they're maybe about 3 inches now?), but I'm starting to notice what might look like pyramiding, and potentially fungus? There are some little white spots distributed evenly across both of their shells. Also, I noticed that the outer edge of their scutes are transparent. I'm not sure if this might be a problem, but it seemed weird to me. I know that they're basking quite frequently, because every time I walk into the room they're jumping off the dock into the water. However, I didn't know until recently about the head-size amount of pellets rule, so I think I've been feeding them too many high-protein baby turtle pellets. (The container that the pellets came in said to feed them more food until they slow down for about 15 or so minutes, which I guess is wrong--they just keep eating away until I stop feeding them.) The other concern is that I didn't realize I needed to change the tank water as frequently as once every week or two weeks--I thought that since I was using a feeding tank, I could get away with a little less. This is definitely something I will be correcting, but maybe the less frequent water changes contributed to these conditions I'm observing. I did check to see if any of the white spots were shell rot, and as far as I can tell, they FEEL okay--they're not soft or sticky or anything--which is why I suspect it might be fungus.
I'm going to cut down substantially on the pellets, get them some cuttlebone and calcium blocks, try harder to get them to eat more veggies (they didn't eat any lettuce, and only a little bit of carrot the other times I've tried), and clean the tank more frequently. What else can I do? Can anybody give me any more information about the pyramiding, white spots, and transparent outer scutes? Am I just paranoid, or am I right to be worried?
The other thing I'm worried about is their behavior, which is becoming very erratic and frantic. I observed that they were freaking out a lot when I first got them in their terrible condition--they were kept in a tiny plastic carrying tank with an inch of water on the bottom, in a shadowy spot in the corner of a room, with no lights, no dry area, no filter, and all the other things you guys probably have nightmares about. When I put them in the larger, clean tank with a light and filter, they calmed down and seemed to recognize me after a while. They still seem to recognize me, but I've been noticing that they get more frantic when they get put into the feeder tank (which is actually the carrying tank they used to be in). They scurry around everywhere and try to swim frantically through the wall. Recently, they've even started to eat a little less, I think. I've tried feeding them in their normal larger tank, which is better, but I still notice some of the nervous behavior. How much of this is just them not realizing what glass is, and how much of it is them being stressed out? What can I do to help them?
I attached some images; if you look closely, you'll see the white spots and the transparent scutes, particularly near the bottom of the shell. And the pyramiding?
Sorry for the long post, but I just have a lot of questions! Thank you so much for any info you can give me!
