wut about krill?
ill overfeed him now
No, you don't want to overfeed him just as much as you don't want to underfeed him- you need to do more research and find out exactly what you should be feeding him and how much/often.
I have posted to you before a couple of weeks back on how your goby was starving, which you denied at the time. Howeever, although you have been seriously underfeeding the goby, it will starve just as much if you don't feed it the right foods.
More importantly though, are you keeping him in a freshwater, brackish or marine tank? What is the temp in the tank? It looks like you are keeping it in freshwater, which is really bad for them;

I hate to say it, but your goby looks in a seriously bad way, it may be too late if its stopped eating completely (often a sign of doom when a starving fish stops eating).
Try getting hold of some frozen bloodworms, the krill should be fine too, but if you feed dried foods make sure you soak them before hand so they sink and are eaiser for the goby to find- not all dried foods sink though, so frozen foods are best.
