Ok, here's the run down. I've set up a 29g Eco complete substrate, lots of slate caves. 2 brichardi, inch or so long, they were super shy first few days obviously. I added 3 LF zebra danios as dithers, which helped get them out and about but they're still very scared of me. My question is should I add more fish to make them feel more confident? What I want to do is just keep one and add a calvus/ comp and a tropheous but I'm not sure singles of these guys would be compatible? Obviously an upgrade in tank would be essential in the long term. What are your thoughts?
