Sand shifting goby & 3 snails in sand

[JennyH3]

I have 1 strawberry conch & 2 super Tongan nassarius snails In my daughters 30 gallon tank.

I would like to add a sand shifting goby. Would the goby and snails be fighting for food in the sand?

if not what goby can I get. Assuming the diamond would be to large. I’ve researched smaller sand shifting: could I do a court jester (rainforord) goby or an Oranet crosshatch. is there another sand shifting goby that is small?
the diamond is my daughters favorite “pretty” wise.

You could get a diamond goby that is eating prepared foods, most of mine that I have kept ate frozen. But yes it would probably outcompete your snails.

Court jester goby is a decent idea, get one eating frozen though. Biota has captive bred ones, definitely the best option and actually not that much more expensive. Probably wont outcompete your snails that bad
