Multiple firefish / midas blenny in large tank

[IOnceWasLegend]

I know the general rule of conspecifics and aggression, but I'm curious. Has anyone successfully kept multiple firefish and/or a midas blenny in a larger tank?

I think my Nuvo 200 should be big enough to minimize aggression between firefish, but not sure whether it's a worthy experiment to try adding a midas blenny.

In my experience...
You can keep gobies in groups
But only single blenny (Algae blenny species complex)
But I do recall keeping at least 3 Ecsenius lividanalis in a medium size tank for a while
(‘‘Twas a very long time ago)

I never had long term success with fire fish so no real knowledge here

A group of 6 Ptereleotris zebra is awesome

I’ve kept a Midas and a bicolor blenny in my 190. They would fight then stop then fight. Until there was a pecking order. Like tangs.

I had multiple algae blennies in my tank for a year or so. They didn't ever hang out together though and all had their own space.

I also had a midas blenny with other blennies, but they had their space to not see each other.

Also had a pair of purple firefish for a long while, but the regular firefish never did well.

I had a totally reclusive fire fish that would only come out to eat, until I added another and then its life mission was to destroy the other fire fish. The new one got stressed and disappeared (probably died and then got eaten or was chased out of the tank).

Appreciate the input, everyone!
