My first true monster

  • We are currently upgrading MFK. thanks! -neo
I know someone who had a polleni turn around and completely slaughter a load of other fish larger than itself. In a similar if not bigger tank. I know my experience is limited though

And i know member that have polleni that are model citizens....see what im getting at
 
True. With cichlids you never know :confused:

Oscars are thought to be mild. I had one wreak havoc in a 150 gal. Would i be correct in telling everyone that oscars need to be kept alone ?

1 con in a 15 gal doesnt equate to all cichlids or all cons bro

I think they are just worried he is dismissing long term expectations for short term success. If he went at it with the willingness to lose the prior inhabitants in the pursuit of breaking new grounds it would be met with more welcome than trying to fit the square in the circle with the hopes of moving it before disaster. I've not kept this species, but with general SA cichlids I've noticed a night and day turnaround for when a species is settling in vs when they are settled in. Add in that large cichlids don't rehome very well and are way less likely to work out than a specimen grown into its environment. A worst case scenario would be him waking up to all his fish missing eyes and floating around while it wags its tail waiting to be fed in the middle of the tank. This scenario still sounds more likely than him proactively rehoming things and ending up without a bloodbath, and much more likely that the RTM will settle in to the circle slot. Just my 2 cents.
 
Cichlids will always be a case of trial and error.
There are no absolutely positive outcomes.
Sometimes a given species will break the mould.Sometimes they will be true to form.
Knowing this, all we really have left is the notoriety of a particular species.In this case the rtm.
Rtm's are a notoriously aggressive species. If you've been involved with cichlid forums long enough you will read many accounts of their aggressive nature.
Can one break the mould? Sure.
Is it likely? No.
If a person were to smoke 40 cigarettes a day,chances are his life would be shorter than if he never smoked.
No guarantees of this,there is a chance he may live to be 100 years old.
The laws of average tell us he stands a good chance of dying younger. Therefore my advice to him would be,don't smoke.
Would I be wrong to give this advice based on a law of averages?I don't think so.
Going by the law of averages with cichlid aggression is all we really have to go by.
I feel the over cautious path is the right way to go with this species. 9 out of 10 will be killers.
As Justarn said keep a divider at hand.

Obviously everyone is just trying to give angelphish Sound Advice... just sharing my 150 gallon when I had both male and female in together the only other fish in there was a pleco... I made the suggestion that the RTM could be kept with other fish but that's only with other aggressive cichlids being that he has a 210 gallon seven foot tank , it could be possible.. with the fish that he has in there now I agree with what others have already said and the only one I would see surviving long term would be the pleco.. ... angelphish has (had)a nice harmonious tank with a lower-level on the scale of aggression cichlids.. I guess we're all interested in seeing how long this may last while at the same time giving warning trying to be ethically correct to help avoid the pending fatalities... I'm just a sucker for any thread that has RTM in it though and am interested in seeing how this goes I feel that based on the type of tank that angelphish likes the RTM won't be the one that lasts.....

If the RTM does go, it'll be to someone on MFK. It will be in a good home regardless.

I agree with everything you guys said. But he did start out by saying he had another tank on hand regardless that his dad wont let him set another one up at that point he knew the risks and of course members were just tryong to help but i just rhink after the first 5 opinions its a little redundant. To me it was needless piling on lol we got guys telling him what to do that havent had cichlids more than a few months. You guys all know me pretty well and know i dont mean anything towards anyone by my stance on this and this isnt directed at anyone individual but at what point does the advice start sounding less like advice and more like a do what im telling you thing.
Dont wanna derail any further as it not my thread

I think because it's an open forum that more opinions may be a good thing. Since anyone can see this information, including people of very different experience levels, providing opinions can be beneficial. There are also many experienced people still chiming in.

Really I just think it's a bit irresponsible given my very narrow view of the situation. Achilles1763 Achilles1763 has a sick fahaka community and received a lot of flak for sharing it. Obviously puffers and cichlids are different beasts, but the idea is the same. Build a community around a species that has a bad reputation, but the way they approached it was very different. He might be a helpful resource, you can catch his thread below.
