Survival of the toughest

  • We are currently upgrading MFK. thanks! -neo
the salvini could very well be the aggressor, considering they are one of the meanest of the small species, and can easily have their way will juveniles of other larger species
 
its could be the jag...as my male jag when it was smaller was a bit** and took on a much larger male flowerhorn...but ended that my jag was just aggressive for the much larger flowerhorn...but it could be the green terror as when i first started fish keeping...i had a group of gourami's...then sold them to get a single green terror for the 55 and found out it was a bit** when i added another green terror but now its one with the white fins and now the common red orange ones...thats the one i got already before the other white fined one....and flared and flared until they connected and lost my first GT to the white one...
 
nahh wasn't the fire mouth some can be aggressive but with those fish if it tried to fight them it would get destroyed

Its either the Jag or the salvini jags can have a bad attitude and salvinis although small are incredibly tuff won't take crap from any fish even if there twice its size you have to be tuff when your small and brightly colored or fast salvini aren't that fast so they got to be tuff and can be pretty aggressive as whell and with teeth to match most likely the sal

The salvini sure doesn't take any crap from anyone. He just swims around and the other fish move out of his way and if they don't he chases them out of his way.
 
I'd bet its the salivini and/or jag. They are 2 of the most aggressive cichlids out there are are just plain incompatible with some of your stock. There is always that 1 in a million time where a combination like that would work, but chances are overwhelming that it would end in several violent deaths (as it did). You yourself even said you weren't surprised, so apparently you had an idea that this would happen, but really thought you would be that one person out of a million that could do it?? I don't think risking a painful and violent death for your fish on the INCREDIBLY small chance that MAYBE yours will be different, just because you 'wanted them', is a good fishkeeping practice. If you want them all that bad get another tank. Just my opinion.
 
jag,jd,gt,firemouth,nicaraguensis,acara,chocolate, and a salvini.
FM nic acara and sal are gona be gonners by the jag and i bet the jag will be teh last fish standing
 
^^ I've never owned a jag myself so I didn't want to say it, but that's what my friend told me also -- a jag might just kill every other thing in the tank till it's the only one left there. He had a jag kill 5 other fish in his 150, and they were all large, aggressive fish.
 
First instinct tells me it's the jag. That being said, I've owned nearly all the fish on your stocklist myself. Fish are individual as you and I. You never know what you're going to get with any one species. I think you went about trying to mix these cichlids the right way by giving them a lot of room and putting them together as juveniles. However, now that you know you have an aggressor, you need to isolate that fish from the group. I would start by isolating the jag and see if the beatings stop. If they do, you've found your problem fish. If not, move to the next stereotypically aggressive fish, either the Salvini or the GT (IMO). Continue until you find out who's administering the beatings until you isolate that fish.
 
Well, the jag definately guards his log but pretty much leaves the other fish alone unless they come too close to his log. Last night the chocolate bit the dust. By the time I got home from work he was done. The green terror and the firemouth are by far the most aggressive while I'm watching them at night. The salvini does his own thing and the jack dempsey does the same. I'm wondering if the jd will get more aggressive as it matures. Don't know for sure if the jd is male or female, it has been pretty dark in color and has good spangling on the head and gill plates, this would I believe indicate a male. I'm thinking of getting a 180g and putting in an oscar initially, let it get acclimated well, then add the jag and some dither fish. That would be all that would go into that tank. Then see if the remaining salvini,gt,firemouth, and jd would get along in the 120g. Think that would work?
 
I do think getting another large tank and separating the fish will help. However, if you end up having 1 rogue killer on your hands, it's possible that particular fish may just have to be alone. I'm not sure I'd put the jag with the Oscar though....jag is pretty much the most aggressive cichlid by most people's estimation, and Oscars are very docile in comparison, and one of the most docile species you have in that tank. Perhaps put one or two of the more aggressive fish in with the jag?
