Hi..I'm a bit stumped and would like to know about the tetra vitashell for soft shell.
I have two RES that I adopted about 5 months ago. They are still baby size but could be over a year old (they were kept in an unfiltered fish dish). They are now in a 39 gallon tank with a canister filter and about 25-50% of the water is changed weekly. They have UVB and UVA .. with a basking area (which they love). They also have a water heater and the temperature is between 76-78 degrees. I feed them every-other day ZooMed aquatic turtle food...everyday they have greens (zuccini and kale)...and I break up some cuttlebone.
The one turtle has grown significantly and has a nice hard shell. But my other guy is still small (about 3 inches) with a fairly soft almost slimy tummy and the back scutes are very flexible. Please Help
