alright... so back to my original question, do you know what a co-dom morph is? i don't mean can you copy a definition from someone's website... if we can assume the tiger is a co-dom morph, which it most likely IS, then what you're saying does not make any sense at all.
just for the record, i currently have four different striped coastals, all from different lines, only one is a tiger... so yes, we all know that there are other striped lines so if you're trying to learn something, don't try and insult the ones that can teach you something.
