Hello, I was in the House of Tropicals yesterday to get some dwarf chain loaches and an African dwarf frog. Anyway, I noticed that they have pastel colored frogs called "tutti fruitti frogs". They appear to be dyed African clawed frogs. There were pink, blue, turquoise, green, etc. Does anyone know anything about these frogs? How do they make them turn those colors? Do they dye them as embryos, tadpoles, frogs? Are they tattooed? Is the color permanent. Most importantly, does it harm the frog? I noticed that there were 3 or 4 dead ones in the tank, but no dead ones in the plain albino African clawed frog tank. They colored ones also didn't appear to be as active. I was at House of Tropicals the previous week, and they did not have them at that time. I am wondering if they got them in for Easter?? Anyway, any info on these guys would be appreciated. Thank you!
