Are Mono's fin nippers?

[FalconKeeper]

I recently added a small Mono Sabea to my brackish tank and he is nipping at my Violet Goby's fins constantly. My Goby is such a pushover he doesn't do anything but run. I've never had any of my fish nip at him until this guy came along. I just finished setting up a nice pile of rocks for my Goby to hide in and the Mono can't get to him. Just curious if it's common for Mono's to be fin nippers?

My argenteus are not aggresive at all. The 3 of them just school together all day.

I'm going to get two more as soon as I transfer them to the 125g but my 55g is pretty crowded right now. Maybe when I get a couple more they will settle down.

Good idea monos are a schooling fish . I will be moving my brackish to my 135g soon. 210g for my cichlids is on order.:headbang2

Sweet :headbang2 My 55g is going to be a my African Cichlid tank a 210g would be damn nice though! As for the Mono I have heard they are schooling fish but I picked up just one to kind of test him out and see if I like it. Other than the fin nipping he's a very cool fish and has lots of personality.

My Mono Sebae picks on my Archer....After he chases the Archer around the tank then he flips out on the Molly's. I think my Mono has a serious problem....He cant get along with anyone....

they tend to be nippy especially in low numbers, which happens in many schooling fish

Its not just yours, I had one that did the same thing. It seemed to mainly chase my archers around and ignore most other fish. My only guess is that they look similar (silver w/ black bands) and tend to be more agressive towards them for that? I wouldn't say they injured them or anything though, so overall it seemed to be a fine fish to own for a community tank.

i sold my 5 monos as there nippin was gettin worse with age, they were constantly after my cloumbian shark

I picked up another Mono last night so now I have three. The largest one has seemed to calm down some but he's not as relaxed as the other two. I will probably get two more and see what happens.

Well in my tank, the Mono Sebae doesnt really look at the Columbian Shark catfish at all. As some of you may already know, I was having issues before with the Figure 8 Puffers beating up on the Columbian Shark Catfishes.

I was thinking about getting a GSP but I dont want a rerun on the same crap again with another puffer beating up on my other brackish fish.

I currently have my SG at 1.014. I am still debating whether to go up and further in my SG levels or wait till my fish get bigger. (Archer 4 inches, Mon Sebae, 5 inches, Columbian Shark Catfish 3 inches, pair of Molly's.....

At those sizes is it safe to raise the SG further?

Any other species I can keep in there that tolerate higher end Brackish eventually Full Marine?
