I'm 90% sure that as long as they are added simultaneously and aren't too close in size you won't see much aggression beyond establishing a pecking order.

You might be able to get away with reaquascaping your tank and adding a couple new firefish then though...

Or buy try adding some that are much larger than the ones you have in there already as this seems to make established fish less likely to get their hate on for the new guy...

I can only speak from my specific experience with paired/shoals of fish and what I've read about firefish.

From reading, I am finding that many sites it shouldn't work but then from talking to a few people who I know with experience keeping them, they say its never been a problem for them. I know I remember seeing tanks too with schools of firefish. Might have been very large tanks though.

In any case, I am now on the look out for a Cherub Angel and I think that will be the fish. Not really the brightest fish but I really want an angel and they are about the smallest I have found and also seem to be one of the most reef safe.

Nice to know about the firefish, I'll consider getting a few more later on then :wink:

One out of three people I have talked to that had Cherubs have said theirs were demons, like killing other fish aggressive. One was just normally aggressive (like my firefish towards my goby, nothing serious), and the other was a sweetheart... so I guess it just depends on the fish and the tank. The super aggressive one was in a 30 gallon and was already established, the others were in larger tanks and added after other fishes. I like them though, they're pretty fish (and the size is perfect).

Good to know. I will have to keep that in mind. I have a feeling in my tank it could be a little aggressive because its relatively small and not a lot of LR.

The other option is to just leave the tank as is :biggrin: because Im not kidding, I have yet to see any aggression what so ever other than the jawfish trying to eat fish that come near his cave :D errrrrr...or maybe he is just defending it ;)

When I was asking about adding 4 grammas to the same tank, people treated me like an idiot.
I got so turned around with misinformation; like being told that grammas are hermaphroditic for example when thats simply not the case...

At least with a smaller tank, if a new addition does go aggressive it's a lot easier to remove the aggressor than in a larger tank full of LR.

IMO though, add a gramma or an assessor and you will still have 0 aggression.

Always seems to be another tough decision around the corner in this hobby.

J&L have some Yellow Assessors right now and I am going there tomorrow I think. I will take a look. Tank raised too.

and on sale for 79.95...
wow...


I just had a thought too...
what about a pyjama cardinal or two?

Is that considered cheap? I'm all scared to fill my tank now...

That was actually an earlier thought as well. I was thinking Bangaii but they can get aggressive I guess. Are Pyjama's better?

I am going to go see the assessors today I think :D

I think the regular price for that fish is about $110.
