We got Greek Tort "Rocky" 4 weeks ago, and Golden Greek "Marigold" 3 weeks ago, hatchlings, but I don't know their ages. I weighed them 3 weeks ago, Rocky was 30.5 grams; Marigold was 19.8 grams. Today, Rocky is 37.2 grams, Marigold is only 19.5, which has me worried. I have not had Marigold checked for parasites, but after reading other postings here, I'll do that. But is it possible that Marigold is just taking longer to get adjusted? She eats okay, but does not attack her food like Rocky does, and is not as coordinated at holding down her foot and tearing the leaves. (we've assigned "she" and "he" for conversation sake but have no idea). She poops and pees, climbs and digs and responds to my voice, in general seems fine, tho not as energetic as Rocky. But he's a little over the top, I had to line the inside of his tank in the first week; when he started to see his reflection in the glass he started charging the walls, and chasing back and forth in the tank - it was crazy. Seems like a very aggressive little boy here. Back to Marigold - is there anything else you think I should do, other than feed her more often, and monitor her when she eats. Maybe dehydration? Rocky likes to sit in the water now and then, but I put her in the water and she get out immediately, so I haven't been forcing it I should probably be more regular with her soaking. When will I know I have a REAL problem? Thank you.
