I know these pics arnt the greatest.... My camera died right after them... Any way.. These where sold to me as (spotted/stripped Needlenose) They have some purple on their tails and alittle on there mouths. They had a bigger one in the display tank. With lots of purple.
Looks like Luciocephalus pulcher aka crocodile fish and pikehead related to Gouramis. Gets to about 8" its a piscivore and also a mouth brooder. Might also be a Luciocephalus aura which is a smaller cousin to the pulcher.
