I had one maroon before he was mean! Bit me every time I put my hand in the tank. He would boss the other fish around of they came to the coral he was hosting but other than that he was peaceful. Had the maroon with firefish a damsel and dragonette and a neon goby.
What can you put in there with the Maroon? Not your fingers! Lol. Sorry... couldn’t resist. Re-home it to your LFS and start fresh, I say. Best wishes.
I kept a snowflake eel with my gold stripe maroons in a 72g bow tank
Female killed any other fish she even killed the first 4 males I tried to pair with her
This combination works in my 60g fish-only..... Been joined together in the "fraternal bonds of tankhood" for three months. They seem to be really good friends.
