Top spot in my tank.

  • We are currently upgrading MFK. thanks! -neo
The jags are somewhat mellow when juveniles, but as stated already they become more and more aggressive. IME they typically tend to run their tanks if housed with the fish in ur stock list. In a 55 gal the mix is not likely to last too long, so I'd suggest u start making arrangements for when things turn for the worst. Try getting some ditthers too.

And btw welcome back!

Have you not read my other posts? We have 17 now, including, 5 x 55, 75 and 150 gallons tanks. Each one is cycled up and ready to go.

the jags themselves will need bigger than a 150 for life...

Im not one to EVER suggest the BARE minimum, but I think that theyd be ok in a 150g if its the 6ft tank (72 1/2 x 18 1/2 x 28 1/2)...especially if they start spawning at a small age. That will hinder their growth rate speed substantially.

Thank you they have started the whole mating thing but I think they are way too small to spawn for a while. Tarri

Hi, I am returning to the hobby after a 10 year absence. My husband has never had fish, but has picked it up very quickly. We have a lot of different temperments. At first they were all together now we have Split them. We have all of the aggressive in 1 tank, 2 jaguar, 2 dempseys, and 3 green terrors. We keep reading about how mean the jags and terrors can be but the female dempsey runs the tank. I have never had any of them before. I am wondering if as they grow will they become the nasty fish I. Keep reading about? Befor we moved fish around a female. Blood parrot ran the tank. They are so sweet now. Thanks for reading

The tank is 55G. The biggest fish is a GT at 3". The other 2 GT"s and the Dempseys are 2" and the Jag's are 1 1/2 ". I think all 3 GT's are male but not sure how to tell. And for that matter not for sure they are true GT's I will have to post a pic and see what you all think we think they might be Blue Acara. The Dempsey's and Jag's have both paired up. I am trying for pairs I want to breed, I will move them when I need to. I was trying to find out if it was common for the female fish to be the boss of a tank with all aggressive fish? That is why I posted this it was not to hear who might kill or eat who I know they will change and get meaner. lol But thank you and I don't think I will have a hard time selling the Jag's I don't like the way they look so much grow up lol. But I do want some babies first. Tarri

I've noticed that on a number of your threads and posts that you have come off very defensive or dissatisfied with member comments. Most people are just trying to help you. If you build a bad reputation on here you will find it hard to get any helpful answers to your posts. I know that you have just come from another site that you met criticism and maybe some rude comments, but carrying that over here will just start you on the wrong foot again. Just ignore the comments or members that you feel are not helpful. You are getting answers to the questions that you have asked. You have a few conditions in your tank that effect one another. That's why you are getting the responses that are being posted. Females can often be more aggressive than males, especially if they mature faster than the other males in their tank. If they are ready to breed they will challenge the strength of males to see which is suitable to breed with. This can be viewed by some as aggression. The same goes for maturing males too. Fish of the same sex may attack or kill others to get rid of competition for breeding and territory. The dynamics will change as all the fish mature, males get larger, and territories are made. This can fluctuate depending on the species that you ultimately keep together. Jags are typically more territorial than they are straight out aggressive (most of the time). This is something that you will see as they become older and larger. And I have seen Jags spawn at 5". Green Terrors and Jack Dempseys can go either way, aggressive or passive. But IME Green Terrors are more aggressive than Jack Dempseys. My JDs of the past have all been shy and reclusive. But there are a few members that have experienced the complete opposite. So will your fish become the nasty fish that you have been reading about? Well, that's hard to say. A lot depends on how they are kept and with what they are kept with. Personally, I believe that your most aggression will come from a breeding pair of Jags and GTs. I hope this answers at least some of your questions. I wish you the best in the hobby. And enjoy MFK!

I've only had one Jag that was an outright killer. My others have only been territorial and defended their space. My experience with GT's is they're aggressive all the time so much so that they often will bite off more than they can chew. Never owned a JD, they've always bored me. Whether or not your will grow up and become nasty depends on the fish. Any one of them may or may not be aggressive....individual fish even of the same species have different temperaments.

Your punctuation is off. The two green sentences should only be one...same with the two yellow sentences.

And you must have been extremely defensive and dissatisfied if Al is grooming you on forum etiquette. :ROFL:
 
Well from what I have experienced, just enjoy them growing. Do the research on the temperament of your fish and adjust accordingly. I raised 2 jags in a 150 with several larger aggressive cichs. The jags started at 2" while the average size of the Devils, Hogas, FM, Xilo, Demp & others were around 5". The jags have always shared their tank with larger fish. Now my jags occupy a 125 with 5 Umbee. The 2 jags have recently spawned (they are about 6" now), they keep the Umbee's away, and maintain the fry. With NO damage to the other fish. The largest Umbee is my 7" male. I also did the same thing with my Grammode, now he(7") shares a 300 with several larger fish, and he is absolutely the perfect tank mate.

A long story short. Raising aggressive fish and trying to keep them in a community takes some time and practice and learning. Constant monitoring of the aggression and the interaction between the inhabitants. I have a 55 grow out right now that I have several new species to my family, learning to coexist. 6 robertsoni, 3 breidohri, 2 red istlanum, 4 stalsbergi, all are 2.5" or less. The tank is in my office, so I am constantly monitoring. I know that as they get larger, I will have to remove them and introduce them to a larger community.

I have 100's of cichs that have all shared homes with my community of fish. I have several that now live in their own tank with their mate. But I have never removed a fish and gave them its own tank, until it has spawned. I have 2 hoga's spawning right now in their comm tank, and the before mentioned jags in theirs. My pairs of Festae, WC Dovi, WC Devils, Zonatums, Xilo, WC Hoga's, and Red Islates all have their own tanks, due to their aggression during spawning. If my jags or other hoga's get out of control, they too will be removed or divided. But I doubt that will be necessary.

You just have to learn what works. It takes time and patience.

Welcome, good luck and enjoy. I would not move any of them for some time. Let them experience the company.
