Safe Mix for 150g

[SkunkBotia]

My 150g (72x18x25) is sitting empty and it's killing me. I may be getting bored with fishkeeping because i have spent the last 2 months trying to figure out what i want to put in it and i have not made any progress. I have kept african cichlids, loaches and all the little fish. I was thinking about Sa/Ca cichlids but i also want some odd balls like polys, clown knifes and maybe an aguilla aguilla eel. Here's what i found i like, which can i mix safely?

Green Terror

Green TX
Red Devil
Oscar
Clown knife
Some sort of poly
Eel
Yellow Bullhead catfish

Feel free to throw in more suggestions

I never kept any of the other fish for ore that a few days but my 6" yellow bullhead is a real punk so he ought to be able to hang in there with those tougher fish if he has any size to it.

For the eel I suggest a fire or tyre track.

I think you will be rolling the dice. I have had it where there were very few issues, but I have also had it where one dominate fish destroyed everyone.
