I bought this guy at my lfs. They are not sure of his identity except to say that he looks similar to a texas. They had just received a new system (bought used from petco) and were in the process of installing when they found him in the piping. He survived for a week in the water left in the piping. I have had him for three weeks now and he seems to be doing well. He has decided he is in love with a flowerhorn juvie in my tank 
Looks like a texas to me too...
