Single Green Terror ok in a 75g?

  • We are currently upgrading MFK. thanks! -neo
Compare that to what would happen if a similar sized pair of red devils (or dovii, festae, etc.) were spawning: It would be lights out Vieja and other random fish in that tank. Or they'd be packed into the corners. GTs just aren't on the same level of aggression.

Back in the day I kept GTs with Frontosa, haps and peacocks.

The other question is also was their fry in the tank, or was the male just trying to impress the female? Not enough information, and the video tended to be short so we do not know what could have happened since the trigger was removed. One video does not equal every mating pair's exact temperment. You probably should admit though, considering the difference in size that really is fairly impressive even for his claimed docile Green Terrors.

I think you happy-go-debating people right now is derailing the thread. The thread was "is it ok to have a GT in a 75 tank?" Most said ok, it's fine. So what's what with the who's aggressive when keep with other fish, do make another thread about the topic for your convenience. Keep it civil people. Thanks.
 
I used to keep a breeding pair of GT in my community 75 gal with haps, leulupi, Juli, and a Nic. The pair would spawn once to twice a month, often right after a water change. They would protect the spawn vigorously, but had never injured any fish because they would back off as soon as the intruders left their boundary. The pair stopped breeding after 2 years and died shortly afterward, practically from spawning to death. Now, I separate the sex of my GTs unless I want them to make babies for me, which will not only reduce aggression, but also prolong their life.

GT's aggression is a normal breeding behavior to protect the spawning site. I don't even find them territorial outside breeding time. GT aggression is level of different from Amphilophus species which are aggressive at all time with the objective to claim the entire tank space, including the owner's space, their territory.

Now that the original question has been well answered, comparing notes or experiences seems a natural extension of the conversation imo. It's hardly uncommon for a thread to have such twists and turns, but I'm not the original poster and can't say whether any of this additional banter is of interest to them or not. Certainly, if the OP feels we've gotten off track I'd absolutely respect that.

As far as GT versus other types of fish for aggression, no, I wouldn't put them top of the list as a species when there are obviously bigger, meaner fish out there with bigger nastier teeth, etc. But, as most us find out, cichlids can differ widely in individual temperament and the general rules don't always apply, so we can't always extrapolate a general rule from personal experience. That's the value of getting a variety of comments imo.

...I mean, I had a betta once totally back down and intimidate a jewel fish to the point he stayed far out of the way of the betta afterward. On the other hand I later had a 3 inch jewel fish tear up a 9 or 10 inch severum in minutes, would probably have killed him if I hadn't been there to remove the jewel fish (both of these were single lifalili in the respective tanks). Taught me something about jewel fish I didn't soon forget, with the point that might be of value to the original poster being that what happens in one tank doesn't necessarily make a general rule for the species.

Wow after reading through this thread I can't wait for my GT to get bigger. Especially after seeing all of them in that video. Mine is starting to show some more color in the tips of its fins. I hope min turns out like some of the ones I have seen love the body shape and colors.

The thread posts are still related to the original thread; they still apply and they are still relevant. These are reasons to be careful, or why a person potentially can not keep more than one Green Terror or other fish. The opposite is true too, if the op decides to go for it, he or she can add as many fish as he or she prefers. Maybe this topic would persuade him or her to select a different species altogether. You are making it seem like everyone is just supposed to answer with a simple "yes or no". With such a simple question, and simple answers, perhaps the thread should be in the lounge. I presume this question was intended to be expanded upon and further emphasized to help influence his or her decision. That is why he or she asked in the first place, but oh well.

I somewhat agree with you that typically, this generally is more than likely the case. I respect your opinion, and I do not doubt your experiences; just keep in mind that you have or I presume you have one strain, they are not all that peaceful. If you bought them at the lfs, then the likelihood of them being related is increased. If they are fry from some of your batches, then they are almost certainly one strain. Some strains are more aggressive, and this also strongly just depends on the individual fish. Again, fish obtain names like Green Terror, Red Devil, and Red Terror for a reason.
