Regarding Wolf Fish, Payara, and African Tigers...

  • We are currently upgrading MFK. thanks! -neo
Charicins are in the Tetra or "Shoaling" family. They will generally Shoal with any and all shoaling fish including their food. Wolf fish and Piranha are some of the exceptions. Most notibably co-habs work better when large fish are kept in large tanks. The problem keeping Payara and ATF is that alot of ppl want them to live in small tanks ie- 55 gal - even as juvi's it doesnt work - think 200-300 gal or more with over filtration and ample supplies of oxygen. Aggression from the shoaling Charicins is genarally caused by lack of space. What to aviod - large Cichlids, Piranha, Large Wolf fish species, small fish that can be eatin, species of with aggressiveness,Pacu's, and large Plecos because they generate too much waste.
 
i had a wolf fish, when i bought him he was in a tank with other healthy but significantly skinnier fish. while i had him he had his own tank and he was a voracious eater.

i guess what i'm saying is if you're going to keep a wolf fish in a community tank the other fish should be the same size or bigger and you should keep the tank well fed (or at least the wolf fish).

What can or can't I keep with them?

What is their aggression?

What species should I avoid for a comm tank?
You can keep pretty much any fish that is the same size or bigger with them. For African Tiger, they need some room, since they're fast darting, skittish fish.

Which Wolves would be okay for the comm?
Pretty much any wolf fish would be ok for the comm tank. Just beware that they are good jumper
 
in thev same way large Cichlids are personable, so are large predetory Characins. They each seem to have their own personallities and where one Wolf or Armatus will happily live with other species, others will rip everything to shreds. Prime example, from expereince, is the baby Gold wolf i added recently. Both of my larger gold wolves have been intelligent enough, but were never what i considered aggressive or 'hunters'. This little guy is the complete oposite and verging on aggressive. I'll be really interested what it's like when it's a bit bigger.
 
This is a difficult question to answer. There are many factors that can have an impact on the compatibility of these fish, any fish for that matter. Including the individual personality of the fish in question. One of the most important factors is the size of the tank. You can get away with alot more as the footprint of the tank increases.

Is this a general question or are you trying to plan something?

In my experience

ATF's: Generally safe but there are exceptions. They don't usually get on with each other unless there is a decent number of them, I had two in an 8' and had to remove one because of constant aggression. This tiger also destroyed two Tats. It is now fine with two large Brycons. GATF are similar but because of their eventual size do require a much larger environment.

Payara: Scomb are easy to keep with other fish but are relatively delicate. Tats are a really good option I have two in a 5'x2' with a number of fish including a shoal of SD's, They can be aggressive to each other if there is a low number of them but doesn't come to much other than occasional chasing. I have not kept armatus so can't really comment on them but they are known to be more aggressive than Tats.
Wolf fish: The Erythrynus group, Rainbow, Red wolves are pretty safe with anything too large to eat, they will however not tolerate their own kind. It probably would work in a very large tank. Hoplerythrynus, Gold wolves are fairly social and actually shoal and hunt as a pack in the wild. The Hoplias group are different however. As with most of these setups there will be exceptions. The Mala group is a difficult one, this is one of those personality things. Some seem to be ok with others some don’t tolerate other fish. This is probably down the fact that there may be a number of species under the Mala name. The Lacardae group, lacerdae, curupira etc. seem to be more stable and usually tolerate fish too big to eat. There are plenty of examples of these fish being kept with others. Aimara are in most cases a no no with other fish. There is a video of a large example being kept with some Exo’s, I have no idea how this has worked out. I have had mine attack anything in the tank including rocks and myself.
This is my community, ATF, Hoplias curupira an some others. http://www.youtube.com/watch?v=saifaP2HmG8
 
Reasons I'm asking a question is because I do plan to make a tank, so I really want some info on these fish. Especially in regards to aggression.

Likewise, my characin knowledge isn't all too extensive, especially with wolf fish, so I was hoping to get some info from you guys.

Thanks everyone!
 
What size tank will you have?

As wolves go in a relatively large aquarium you can't go wrong with a Hoplias curupira, Black Wolf. If you have enough volume a couple of Dorado would be awesume
 
8x4x3.

Was asking in regards of sociability to see what I could or could not potentially comm. Was thinking of making a Mega-Sized Version of your standard comm tank by having it be just cyprinids, characins, catfish, and any other rather large fish that can socialize and are not part of an oddball family or something.

Any tips for that?

And in regards to the Curupira, is it aggressive as all heck?
