Can I put....

[Sunshine]

I have a Green Mandarin Dragonet, Yellow Watchman Goby and a Red Scooter Blennie.
Can I put a Long Finned Sleeper Goby in the tank also ? It's 90 Gallons.

The gobies will fight with each other.

Also, your dragonet and scooter blenny will be competing for food, since they both almost exclusively eat microfauna like pods. One or both will most likely starve to death in a 90g. :(

What other sand sifter can I put in there with the ones I already have ?

Sand sifting star fish, but I think those eat pods. The mandarin will starve.
