Snake Skin - German Red Lace Round Tail
I personally like this cute short round tail guppy which is so active when the male gets older. This short tail type of male guppies have a less tendency of a hunch back unlike the delta tail counter parts.
It is also less prone to tail burn or fin rot as compared to the big broad fan tail guppies. It is a good choice for people who have little time to care for their guppies or newbies who are starting off the hobby to fancy guppy.
