Will this work in a 180?

  • We are currently upgrading MFK. thanks! -neo
This is me trying to spark up my fish life! :)

Thing is I already have most of the fish and they have been living well together (jag goes through stages of being a sh*^head) for the past year. All the fish are reaching adult stage: The Oscar is the current boss at over 30cm, Jag 24cm and the female GT and male Jack Dempsey are 18cm, BGKF 30cm+ and the 2 cuckoo cats are 18cm.

What I want is this: A tank with all my favourite Americans of my favourite sexes. Sounds simple enough, right? :P The other Americans I don't have which I would like to get (most of which I've owned at some point, and had in this tank) are:

Carpintis Escondido (Male)
Replace the female GT with a striking male GT (Gold Saum)
Red Salvini (female)
Female Festae
Male Firemouth

So you know what I have, what I would like to get.... What would you do??

kinda like this...NO festae though...WAY TOO agg....
 
Yes it's a Black Ghost Knife Fish. He's become really personable, swimming at the top of the tank to get food and showing the Featherfin cats who's boss.

Well I might give it a go. I live in Australia so it's always difficult getting the fish your after, but I'm going to replace the female GT with a male with a lot of gold, get a really blue Carpintis (Vontehillo) and a female red salvini. I'll pass on the female festae and male firemouth- and keep them as ideas for backups if any of the fish don't work out.

I'll have to add them at different times (due to the trouble of actually finding the ones I'm after) and reshape the tank layout and territories before each fish goes in.
 
Well I bought the carpintis, all paid for just waiting to move then pick him up from the local store.

You can see him here (half way down labelled texas): http://www.qldaf.com/forums/sponsor-sanctum-26/some-weeks-stock-76329/

What sex do you think he/she is?

I'm thinking about replacing the male jaguar with a male firemouth. The jag is absolutely beautiful but he's pretty aggressive, shooting forward from his hole at the other fish, the oscar has a few marks on his face (which will heal). It's such a shame because he's my favourite fish, but I'm getting to the stage where I would rather a few more of my other favourites (salvini, jd, gt, firemouth, texas and oscar) coexist than just him. I knew the risks getting him, but it still does suck letting one of your favourites go.
 
Like what Riftraft said, this is a puzzle that you need to do in a trial and error basis. Sometimes it may work, sometimes it may not. For my community, I got less favorable combinations before I reached a considerable amount of peace. For the Oscar, it should be the largest in the tank. Soon when the jag reaches a similar size with the Oscar, problems may arise. For the BGKF, I am not sure, I recommend not to even put it there. Knives are nocturnal and your other fish may be stressed at night specially if you do not have enough hiding places. Knives also do not back down when confronted by other fish. I threw my carpintis away (gave it to an LFS, I mean). That stupid fish is unreasonably aggressive and annoying, goes to my cichla's when they move towards his view and bites them by their eyes. The LFS put it with 20 other red devils in their tank so he must be sleeping soundly now. With that said, each fish has its own personality and you may be lucky enough to find mild tempered fish.
