They need really soft and acidic water (like think around 5-6 for pH) otherwise they tend not to thrive. I have kept coccina in the past and keep many species from that group and they are one of the more delicate and difficult group of species to keep because of that.
I can't really tell from that photo, but if you want more info on keeping B. coccina, check out my website in my signature. It has a ton of information on housing and caring for these fish.
