OK something is really going wrong in my tank. Some of you might remember i had to remove a clown that was starting to bother everything. Well then after that some of you might remember i had to remove a coral banded shrimp becuase it ate my band new purple firefish. well yesterday i bought a new firefish to replace the one that got eaten. Just my luck that this one darted behind the rocks the second he was in and this morning was still hiding. i found it weird because i heard these fish like to stay out front and my last one never hide in the rocks. well what i saw just moments ago has amazed me beyond any of the things that has hapened so far, i really coudn't believe my eyes. I saw the firefish FINALLY come out just a few minutes ago and i was like, ok good, it's out now and everything is ok with it. but then , out of all things, my LAWNMOWER BLENNY started chasing it and bitting it vigurously i mean to the point where i thought he wanted to KILL the firefish. i have never seen my blenny or any other blenny for that matter, be so vicious!!! what is going on with my tank why is everything getting so aggressive. i mean arn't blenny's peaceful fsih?

Remember that gobies (which a firefish is a type of) and blennies have a close structure resemblence and tend to be territorial. Try catching the blenny, removing him for a few days or weeks til thee firefish is comfy, the put him back in. Or you could catch them both, rearrange the rocks & re intorduce them both together. Lastly, try puting a plexi glass divider in the tank separate the two, one on each side & after a few weeks, remove the divider. They should end up being fine either way.
well the divider sounds good but i cant do that just becuase the way my rocks are set up. Im having a hard time catching him to becuase im trying at all cost to avoid taking my rocks apart. It took me a long time to get them the way there are now and i dont think i can do it again lol. so im stuck right now

Blenny's are usually very calm and peaceful fise but if you introduce a fish that appears to be the same size and shape as it they will get territorial. I would buy a $4 breeder net and put it in your tank with either the firefish or blenny, which ever one you can catch. Let them get used to each other for a few weeks and then put them together.
I hope that helps.

Hey J, sorry to hear of these issues your having with your fish man. You've seen my purple firefish in my tank and it's "always" out swimming around when the lights are on. When they turn off he goes to sleep. Not to mention I have "no" glass tops on my tank and he's been in there that way for over a year.
Knock on wood of course.
