I think Sammie looks like she may be gravid. Spice has filled out nicely, and the two little yellowheads look nearly identical LOL.
The red head still looked fine this morning. I haven't had a chance to investigate the foot anymore...still wrapped up and clean though. These guys eat a lot more than the collareds. My male red head will come out of hiding when he hears me, then start peering into his dish to see if I left him any treats. He will take super worms from my fingers.
He really chews his food...he will chew a worm into three or four pieces...sometimes leaving the pieces, and other times he will pick them back up and eat them too. Still have two gravid female Tanzanian Red Heads.
