So they're tails are always the same color as the inside of they're ears so is the webbing in between there fingers. NEVER NEON COLORS!!! The neon colors do not look good on these guys! Pastel and dark colors are okay though! They're mouth is the same color as the lightest color you used (White doesn't count) They have about 2-3 ears on each side. They act like dogs but swim like axolotl's.
