Oh man, I have a bunch of micromussas. I'd be mad.
Sometimes, adding a more aggressive fish last can avert the aggression. But I don't know once they make themselves at home. Sometimes that changes. This is my third diamond goby I have. The first one had some parasitic arthropod on its tongue and I couldnt catch him, he wasted away and died.
Then the second one was too small and got murdered by my red belted anthias....now I have a third one and he's doing good, but he's making a freaking mountain out of the left side of my tank and for the past week or so, I have to push all the sand back...and then he starts again.
Some of these blennies and gobies are real bungholios if you know what I mean.
I'd like to add an algae eater, but the starry and redlip can be jerks. I don't want to lose 2 for the price of 1.
I wish all these fish would just mind their own freaking business and do their job!!!
