well wouldnt it be nice of we all could live on a tropical coast where shipping these delicate animal from store to store is much less of an issue. Bragging about it makes you to be truly well Im gonna stop myself right there. So to you people bragging how little you pay, i hope you feel good about yourselves, Im in upstate NY, and a hippo is never under 50$ for a tiny .5"-1.5" larger ones in the 100$ range skunk shrimp @ least 40$. But even though the prices are way too much, Id take NY over CA any day, people are just so much nicer. Now to the question about the hippo, Ive dealt with many of them before, they like to scare people into thinking theres something wrong with them. Ive seen the color change you described many times on both my yellow belly, and my regular hippo, dont be alarmed. Only worry when they get parasites or stop eating, b/c they love to eat and they are ich magnets
