Tank mates? Tank sizes? Lots of Advice Needed!

[Papa Bravo Zulu]

I am considering the purchase of a 190 gallon aquarium...

REQUIRED BACKGROUND INFO​

My current set up consists of (all of my tanks have at least 2 to 4x the recommended filtration)...

1) 75G with 5 - 2" spotted SD's, a 6" Striped Raphael Cat, a 1" Striped Raphael Cat, and a 5.5" Tiger Oscar.

2) 60G with 1 - 3" Red Jewel, 1 Firemouth, 2 Green Terrors (Gold Saum?), 1 Jack Dempsey, 1 American Flag Fish, 1 Spotted Raphael Cat, and 6 Australian Rainbow Fish. (Eventually overstocked I know but all fish other than the Jewel are 2.5" or smaller). I want to re home some of the cichlids into the 190. Recommendations?

3) 55G with 1 American Flag Fish, 6 Denison Barbs (Roseline Sharks), 1 Rainbow Shark, 3 Odessa Barbs, 4 Zebra Danios, and 7 Cory Cats (all of these fish are juvenile)

4) 37G with 2 Pearl Gourami, 2 American Flag Fish, 4 Humphead Glassfish (one of my favorites and the fish that got me started with fish-keeping), and 5 Cory Cats.

GOALS​

The primary goal of purchasing the 190 would be to eventually re-home/intermingle some of the cichlids that are currently in the 60G.

The secondary, but unlikely, goal would be to also home a Red Terror and/or Tiger Datnoid with some of the fish in the 190.

CONFOUNDING VARIABLES/DRUNKEN BLUNDERS
​

So I may or may not have had a little bit too much to drink Saturday night, came home, and ordered some small SA cichlids (all 2.5 in or under). 2 Orange Shoulder Severums, 2 Red Ceibal Cichlids, and 3 Gymnogeophagus Ex-meridionalis Cichlids via Aquabid.

If I indeed did make the aforementioned blunder, which tank/tanks would I want to temporarily stock these new fish in?

CONCLUDING QUESTION(S)

​

Which of the new or old cichlids should I put into the 190 gallon tank? Do I stand any chance of keeping either a female Red Terror or a Tiger Datnoid in the tank along with the proposed cichlids, or do I need to get yet another tank to accomplish that feat?

Thank you in advance for all of your help.

​HELP!!!

The ceibals and Gymnogeophagus are sub-tropical species, they require a short cooling period, and for at least part of the year, should be in a separate tank from the others. They seem to show best colors after the cool down.
Although I have mine in a cold basement for a few months in the low 50s'F, a tank without a heater that drops into the 60s would probably be adequate.

2) 60G with 1 - 3" Red Jewel, 1 Firemouth, 2 Green Terrors (Gold Saum?), 1 Jack Dempsey, 1 American Flag Fish, 1 Spotted Raphael Cat, and 6 Australian Rainbow Fish (Eventually overstocked I know but all fish other than the Jewel are 2.5" or smaller).

​

Thank you Duanes! Would the 60G be permanently large enough for the 2 Ceibals and 3 Gmyno's?

Would the rest of my fish in the 60G (plus the two orange shoulder Sev's) all theoretically be able to coexist in the 190?

Does this basically rule out the idea of a Red Terror and/or Tiger Datnoid in the 190 as well as the other Cichlids?

Which tank/tanks should I temporarily house the 2 Orange Shoulder Sev's, 2 Ceibal's, and 3 Gymno's in?

 

[duanes]

I have kept ceibals and Gymnos together in a 60 gal, they are relatively slow growers, and don't get too large.
For life, maybe, as long as the ceibals don't decide to spawn, that's when they tend to get aggressive.
