Diamond Goby, scooter blenny, and engineer goby - need input/advice

[Pola0502ds]

I want to add these 3 fish into my 75 gallon tank that has been established for 18 months. Already have 2 tangs, 2 clowns, a wrasse, and a chromis. I have a established fug in the sump, it has hundreds of mysis shrimp in it of which they make there way up to the display tank all the time.

I just wanna hear care tips on these fish, what you like about them and what you don't. Feeding tips? Anything in general about these fish would be great to hear.

Just realize that Engineer Gobies can get large and they like to dig up the sand. I've had 2 friends that their gobies cause lr slides in their tanks due to them digging out the sand under the lr. They are also hard to get out of a tank when they become so destructive. JMO
What type of wrasse do you have?

If you (properly) built your rock up from the glass bottom, then an engineer goby is doable; if you put the rocks on the sand then you're asking for trouble. Diamond gobies are awesome, but nit all of them learn to take prepared foods.
