Sand sifting goby

[wrestle1952]

Can anyone tell me what sand sifting gobies are LEAST likely to jump out of a tank? I have a 100 gallon tank and have had two orange spot gobies jump, a 60 gallon tank that had a diamond goby jump out. I want to keep my sand clean but can't afford to have fish that are hell bent on committing suicide. :sad1:

I've had two yellow watchman gobies over the years and neither one has attemtped to jump out of my 30g. Have you tried a top for the tank? Egg crate or a bird netting are two choices. Some fish can slip right through the egg crate though.
