mandarin not eating well

[bhelne01]

I have two green mandarin gobies that i have had for a 1year now the male i have had longer( 3 months longer) and I am now noticing that he is either losing weight or not eating as well as the female does. the female will eat EVERYTHING IN SIGHT and the male will continue to roam around the tank looking for copepods
what do i do

 

[sanchoy]

quarantine the male.. provide pods, frozen (if he accepts). Looks like the fat female is hogging everything.

how big is the tank? i only have 1 in my 75g and i dont think my tank could support another

A 75 g is marginal for one, inadequate for two. Despite anecdotal stories to the contrary, long term success requires sufficient copepods.

i had a 30 gallon and they were doing fine. now i have a 90 and the female continues to eat well and the male is not doing as well
