What other fish are in your tank ? Even if you get a fuge and supply it with alot of copepods it still may not be enough. Example:wrasses constantly hunt copepods too. you add a six line in the mix and survival rate goes down even more. I congradulate the success and wonderfull picture of the member above with his mandaron but you have to be dedicated that you will commit that time to the feeding no matter what is going on in your life. Its a hard task and without that your fish will die. return the mandaron and keep the scooter. The scooter will adapt easily to frozen foods, best brine shrimp. Good luck, that fishes life is now all up to you !
