Substrate cleaning with burrowing fish?

[Greg1611]

Hi everyone
I've been wondering...

I want to give my tank a good clean, but i have a Goby and a Blenny who have made burrows/homes under my rocks.
Is it bad for them if i move the rocks covering their burrows and disturb the sand?
Like so they will have to re-dig a new home once im done.
Or should i just leave the rocks in place and clean around them??

Any advice is much appreciated

Up to you, I've moved the rocks occassionally, the fish will dig itself a new cave.

You could throw in some nassarius snails and conchs and let them do the job of sand cleaning for you.

I just vacuum around the rocks and stuff. I don’t disturb them for cleaning
