I'm concerned about my two res turtles. I have a yearling that's about1.5 inches and a 3 yo who is 3.5 inches. I'm concerned my three yo, Spotty, has a stunted growth because for two years we didn't have a uvb bulb or heat bulb for basking. However, we now do have a uvb and basking bulb, but my yearling, Lizbeth, is still significantly undersized, because I read online that a one year old turtle should be at least 4" long. I feed both of my turtles a very balanced diet of ReptoMin, Fluker's Buffet Blend, cuttlebone, reptivite(for supplement) ,crickets, feeder fish, and mostly romaine lettuce and other greens. I only feed them once every two days, with greens and cuttlebone readily available.
Attached are some pictures of my turtles. I would like to know whether my turtles have stunted growth or just grow slowly, and if there are any shell problems like pyramiding? Also, my older turtle, Spotty, does have a bit of shell curl and I was wondering if it will go away after time? Another concern I have is if it looks like they are being overfed, underfed, or being fed just right?
All responses are greatly appreciated!
