Talking 75 Gallon Tank.

The tank has yet to be tested for leaks, but it should be fine. Maybe I shouldn't have made this thread so soon, going to give myself bad luck. But you all know the feeling, right?
It has a canister filter too. I believe, that is overfiltering, I've yet to pick it up though. I was told the tank was 90 gallons but it's 75 so we'll see.

-> The tank is 48" long, 18" wide, and 20" tall.

I loooove lake kutubu rainbowfish. That's all I know. I have good water for them too. I don't want to play around with parameters in a tank this huge however, all that distilled water would cost me a fortune. The pH is 7.6 and hardness is 13dH with my other tanks.

If possible, I think I want to build the tank around the lake kutubu rainbow (this is what they sell as a "turquoise" rainbow fish, right?)
I also love emperor tetra.
Curious what could live with the rainbows though.. I would love a group of 6 angel fish, but I don't know if there's room for 2 schools of larger fish in the tank, and if the two are compatible. I know angel fish are "soft water," but by this point they should be fine in my water after all that captive breeding.

Maybe a pair of kribensis? I take the tank is large enough that they can have a comfortable territory and not pose too much problem. The like rocky places to live, right?

I kind of lose myself with stocking.. would this work?
8 kutubu rainbows
6-7 Boeseman rainbows OR angelfish
2 kribensis (or 4, with two little cave things built on opposite tank sides?)
10 (or more?) emperor tetra
Something for the bottom.. 10 cories of a sort, a larger species for sure. However I DO love all catfish so open to something else, even things that hide and I may never see.

Yay or ney if it's too much, or if I could easily fit more. Or at least upping school sizes a bit if no room for other species

From what I can see, there shouldn't be any problems with this (except angels and kribensis, wouldn't put those together, and my dilemma of if I can fit 2 larger species in the tank at all).

Other fish I do enjoy are glass catfish, hatchet fish (my store has marbled ones in now!), loaches (medium size ones for the tank?), odessa barbs, butterfly fish, and honey gourami...

-> I'm also really digging this thing, and I think I've seen them around, but I'd have to change the stocking a lot if I went this way (fish would have to all be at least 3 inches right?):
Leopard Ctenopoma (Ctenopoma acutirostre) Profile
If anyone has insight into this wondrous animal, I'm all ears. There seems to be a few similar fish in the trade and I wouldn't want to end up with a monster, that's always a concern for me.

Again, I stock small tanks, not big tanks. So I am quite confused by this all.
Wish me luck on the "Will it hold water!" test! The tank is in great shape though, but used tanks, right?

Also, it will be nice and well planted and pretty.

Thank you! Yea it was only $40! It's a neighbor that's a friend though so he let me have it cheap.

I'm liking the ctenopoma more and more after watching youtube videos of them... So emperor tetra may have to go, and I don't know what other changes I'd need to make.
I'll have to write the name down and show it to the fish shop guy because I have no clue how to say it's name. xD
Doesn't seem to be anyone on today that can help me?

They're two different species, but think I know which one you're talking about. Leopard Ctenopoma (Ctenopoma acutirostre) - Am I right?

55 gallon planted tank, starting over!!!( looking crappy, needs a major rescape)

Yes, well that's the one I've been looking at since it's on our profiles...
It's a cool fish, I hope I could find one!

Do you have any idea how the stocking plan in my first post sounds?

Okay.. This may be final..
8- turquoise rainbows
6-7 angel fish
1 ctenopoma
8-9 sterbai (or other large) cories

Is that too much?
Is no one helping because they don't know about the ctenopoma? :(
It's a big sedentary fish so I think it'd be fine..

From the info in our profile of the Ctenopoma (which I revised, and to which jeaninel contributed and she has this fish) I would say no with any cichlids. The Ctenopoma is a very retiring, shy fish; angelfish are aggressive feeders, and territorial, and the similarity in sizes would suggest to me that angels would easily frighten the Ctenopoma.

You could build your 75g around angelfish, a group of 5-7. Carefully selected tankmates. And here I would not suggest Emperor Tetra. I have had bad experiences with this fish, and presently my group of 12 is in my 90g river habitat because they are too boisterous for my Amazonian tanks. Only the other day, I was carefully watching one of the males attempting to fin nip the several male Congo Tetras. After about an hour of this, the Emperoro gave up, and I have not witnessed it since. But this plus my experience with this species in other tanks (and with different fish, the parents actually, my present 12 are all fry that survived in the tank) the males can be nasty. This is a 50/50 thing, I know Mikaila has Emperors with no problems. But my two groups, I wouldn't.

I also would not recommend the rainbows with angels. I think our profile explains why, briefly the rainbow are too active for sedate fish. Aside from this, both fish are largish, and I am one of those who prefer just one type of "centerpiece" fish in a tank, to give that species its best conditions and it will be more at ease and show off better. Remember the territoriality of angels, they own the tank.

My turquoise outgrew my 90 gallon, but how much space fish need to swim is subjective. For me, a large, fast and active fish like a rainbow needs room to be able to swim fast. Once they were grown, they could barely do more than dart around the tank.

I have kept 2 leopard ctenopomas and they both turned out to be quite aggressive. Yes, the profiles all say they are supposed to be shy - and IME they are when they are small. I got rid of the first one, which ruled the tank, hoping to get one that was less aggressive. The second one has turned out to be pretty aggressive too.

125 - BGK, chanchito cichlid, pictus cats, silver dollars, palmas bichir
125 - cichlids (severums, bolivian rams, chocolate), rainbows ( turquoise, red), loaches (angelicus, zebra, kuhli and horseface), plecos (BN, RL and clown), denison barbs, tiretrack eel, pearl gouramis, betta
90 - Congo tetras, african knife, upside down cats, spotted ctenopoma, kribensis, delhezzi bichir
2.5 - betta

I finally get a tank big enough for my dream fish and people still say it's small.

Are all the big rainbows that active, jaysee?

I do not want to build the tank around angel fish... They are not my absolute favourite, and if they can't fit in then they go. But at this rate I may have no choice.

What about the African knife, jaysee I see you have em. Bad idea with the ctenopoma?
How long have you had yours and how big is it? It says on profiles maximum 12 inches, but more commonly at 8" in tanks...

If anyone can't see where I'm going with this, I really want an oddball, but I don't want it to be the only fish in the tank as well. It'd be nice if we could make that the starting point. I know it's pretty limiting as it it. 75 gallons. Limiting. Ugh!
