i must admit the more i look at the head the more i am swaying to marulioides , it is probably just getting its markings early
firstly ornatipinis (are we talking channa or poly) if channa is going to be far to small for the marulioides in no time at all , if birchir then should be good for a fair while poss life , but the sen may stay too small and end up as food .
cheers col
should you get more ? - that really depends on weather you want to try and breed them or not , breeding this guy is not to be taken lightly , if you plan on trying then i would get 5-6 in total and remove other fish , if you take this route i can point you in the direction of an article on how it was acheived for the first time in captivity , if not breeding i would just keep the one channa , luckly marulioides is one of the easiest large snakeheads to keep with other fish . wish you luck on whatever you decide
