Here's a link if u want to see one.

how many could? and can u mix deff kinds ?

 

Yes, you should be able to mix different kinds and not have much of a problem in a 220. And it depends on how many other fish you have in the tank for how many gobys you can have.

 

i have a scopes tang and 2 clowns and a drangon and a green cromis

 

You can always buy my lawnmower blenny, lol. Very good with eating algae.

 

Any tho g eat cyno?

 

AFAIK there are no fish that will reliably eat cyano. I may be wrong, but from what I've seen, some fish will pick at it from time to time but it depends on that specific fish. I can tell you from experience, however, that cerith and mexican turbo snails will.

If you're having issues with cyano, you might want to look into fixing the cause rather than taking a gamble on finding an animal that eats it. I had cyano issues when I first started out and, in my case, the cyano growth was fueled by my relatively high phosphates. I wound up doing two or three water changes over the course of two weeks, siphoning out the cyano as best I could, while running PolyFilter pads in the HOB filter I had at the time. The PolyFilter did an excellent job of removing my phophates and, in turn, my cyano.
