Suitable Tank Mates

[Greer]

Hey,I'm in the process of separating my over-crowded tropical freshwater fish tank.
I have various tanks including a few 4ft tanks, a 3 ft & 2ft, this is what i'm thinking- please correct me, & any relevant tips are greatly appreciated!
 
Tank 1-
 
4 Corydora catfish
3 baby bristlenose
Upside down catfish
Bumblebee catfish
Apple snails
Peppermint bristlenose (large)
 
Tank 2-
young elephant nose
2 young black ghost knife's
young featherfin catfish
2 young 'Yoyo' Loach
2 Kuhli loach
Young flying fox shark
 
Tank 3-
13 Guppy's (male & Female)
Glass catfish (getting another 5 asap)
3 indian glassfish
I also have a male & female apistogramma's
A dwarf gourami & large gourami
 
 
Please give your opinions & advice!

What size tanks are these?
 
First thing I will say is an elephant nose and two black ghost knives in one tank is a bad idea - they are all electric fishes and will be sending out signals  - none of the tanks listed are big enough to handle this situation, they will be really really stressed. Even a four foot tank is not really big enough for a single BGK either as these are big fish - a large 4 foot maybe something like a 4x2x2 120g tank.

All fish are under 10cms at the moment, thanks for your reply.
I know that I will need much larger tanks as they grow, but I more meant just until they grow more.
They are 4 by 2 by 2, I have three that size

What/if any fish could go with the ghost knives & elephant nose? & does that mean the two ghost knives should be seperated as well as the elephant, like 3 separate tanks?

Thanks a lot,
Greer
