Looks like a TSN x RTC hybrid. In the UK these are sold under the name "Leopard cat" in the north. Trade price for a 2" individual is £2.73 about $5.50. One of the worst possible hybrids to grace the hobby IMHO. They were originally developed for the food market.
I could really do with a side on shot and a better look at the tail as the pattern varies quite a bit with these, before being 100% positive. Saying that I know RTC's have been crossed with other species and this experimentation is still going on. Has anyone seen any of the RTC x Pangasius hybrids? Ugly in the extreme!
