So I've run across a million ideas for this 29g tank I've got and I keep changing my mind. As of right now, I've got a single female kribensis, one male and one female pineapple sword (the second female came from the store with some fin rot so she's in a hospital tank at the moment) and what turned out to be a male/female pair of golden wonder killies. There's also a male kribensis but I've got him in a separate tank for now because up until today, I had a boatload of krib fry in the tank and didn't want mom and dad getting it on before I could at least get rid of their old batch of fry.
So, I had been wanting to get kuhli loaches for the bottom, but people have warned me that the killies might eat them once they're bigger. I've got sand for substrate. I don't really want cories as I've already got some in my 20g tank. The killies will definitely be the most predatory fish in the tank, so what sort of bottom dweller could I get that they won't eat? Are there some other type of loaches that would work?
Also, I want a second sort of "centerpiece" fish. I was tossing around the idea of a single ram, apisto, nannacara, badis badis, or even knight goby. Which of these would you recommend, or are there anything else that would work well?
I've got plenty of caves to work with in the tank, so that the kribs and whatever other fish will have their own territories. Any ideas?
