30 year old Engineer Gobies in new tank problem

[Tango451]

Hi all,

I just moved my pair of engineer gobies who are 30 years old to their new tank. There is a red carpet haddoni on the left side and they keep swimming around it/ staying around it and their tails will hit it every once in a while and they react and swim away quickly. :facepalm:

I just want to make sure that this sting to their tail will not be fatal (they are still swimming around) and how long should it take them to start burrowing?

They have been in their last tank for over 10 years so I do not remember how long it took them from before.

Thanks a bunch

Im sure they have plenty of space to avoid the carpet nem. Good luck!

How big is the carpet and how big is the tank?

[Tango451]

the tank is 6ft long - 3.5 ft tall and 3 ft wide. The carpet is a big guy probably bigger than 22" but he is on the back wall and is low to the sand/ between rocks.

The engineer gobies are still constantly swimming (they have not yet tried to burrow)

and they literally will not move away from the area with the carpet - they are staying 2 or 3" from it at all times*
