Tiger Endler/guppy Hybrid-do They Breed True?

[fishnovice]

Seen some tigers for sale at reasonable price. New to endlers though I have guppies
1. If I get a male and female Tiger endler/guppy hybrid-do they breed true(ie.all fry tigers not guppies or weird hybrids)
2. How can you tell they are actually tigers not guppies , esp females?

Sorry not read this forum in a while.

If their true tiger, yes the will breed true with only the odd through back.
You cant tell with females as tigers and endlers females are identical.
But if the females have any colour to the fins then it's not a good sign.
