What sized tank am i gonna need for the following...

Absolute minimum 36" I'd say. preferably 48". purely because they are all bottom dwellers except the butterfly.

Pictus cats need a minimum of a 36" tank.
Redtails need 30" but more if there are other active bottom dwellers.
keyholes need 24".

I have a redtail in my 96l with some other bottom dwellers - a very small (2-inch) starcrown pleco, a weatherfish and a Bolivian ram. The redtail ignores all of them except the ram, which it occassionally chases. If a fish looks even vaguely like a redtail, it will get chased at least sometimes. In this case it would probably mean some conflict with the keyholes, and maybe the pictus. The bigger the tank, the less conflict.

Also with that selection of large bottom-dwellers you would quickly max out the bioload in a 36" tank, which would mean a very limited choice for any midwater fish. Be sure to use plenty of wood, plants etc to break up the fish's line of sight and provide hiding places.




:OT: BTW how's the newt?
 
180l would be fine. That's also big enough for some midwater fish as well.
 
cool... well i was planning on breeding the keyholes, are they easy enough? I might move my emporers to that tank then and up the shoals a little.

If you do then you can expand your emperor shoal to 8-10.
 
ooooooooooooooooooooooo
But i read somewhere that they prefer smaller shoals? And i dont want too many fish bugging the cichlids and their fry lol.

they're not a 'schooling' tetra as such, but will tolerate company. as far as other fish bugging the cichlids, if anything it will be the other way round. If there are going to be fry, then you're probably right leaving the community as planned.
