Not possible RTC/TSN crosses are a aquacultured food fish that find their way into the hobby by accident. Tigrinus are not a fish that is Aquacultured or even seriously commercialy fished. Tigrinus are a pinnicle of keeping big pims why anyone would want to Hybridise such a loverly species is beyond my comprehension. But then again all Hybrids should be banned from the hobby IMHO.dodgefreak8 said:just wondering if its possible or been done?
