They love OSI spirulina nibblers !

Blue world had this guys for a few month and told me they were feeding it mysis everyday and seaweed sheets every other day. So I thought it would adjust easy and eat its routine food right away.

I guess I’ll just be patient I think I over react when I get a new fish and its not an aggressive eater

Thank you everyone for your suggestion :D

Kostas Rule No. 1.
Always SEE the fish eating. Don't buy the story that it was just feed. Ask the lfs guy/gal to put some food in her tank and watch it eat aggressively. If not, pass on the fish.
BTW when she starts to eat other food, put some garlic extract and selcon in her food from time to time to build her up.
Cheers

Ya I have learned the hard way about just believing a fish was eating or was just fed. Since then I always make sure a fish I am purchasing is eating, and if not I'll keep it on hold till it eats.
