I only have Oto's and Krib's, from your list, and can say the Krib's will pick on your Oto's. Just make sure you have plenty of plants for the Oto's to hide in and perch on.
Well I just lost a molly today and everyone is advising me that it is because Molly's need brackish water and I know Oto's can't take salt, so I would guess that they are not too compatable.
Can't comment on any of the others though, if they need fresh water then strike the Molly's if they need brackish water then strike the Oto ?
EDIT: sorry BOD must have pushed the reply button one second after you.
yea i was actually thinkin of not getting any kribs now...or maybe just one ive asked if i can keep one krib many a time and the answer was yes but maybe i just wont get one at all! odnt want it to be lonely but from what ive seen the others should get along as they are mainly peaceful and yes i know this is not always true! but ill give it ago and if it doesnt work ill know i was wrong!
