How easy is it to look after Chocolate Gourami?
In short, no. There are usually 2 reasons as to why they very commonly die.
1: They are very picky about water conditions (soft, low pH, warm water needed). They
may sometimes adapt to your water conditions but often they don't and die.
2: Infections & diseases. I originally had 5 Chocs, out of those 3 died over the space of a few months. (now back up to 6 and havent't lost anymore since the original 3) These gourami are extremely prone to all bacteria and diseases. 2 of mine died from internal bacteria, the other from ich. I now have a whole draw of medications, most of which for my Chocs and do water changes every 5 days, instead of 7. Every now and then, they catch something new. They are quite challenging I must say. Plus their main diet still consists of live food which is a bit of a pain
I'm not saying they'd be impossible to keep in a community setup (I think carlovel has some in his)
I had my Chocs in a community tank to start of with (I wasn't originally planning on keeping them), but since they came with various diseases,needed slightly different conditions and were an unexpected addition, I soon moved them them to a spare tank, where they live some Boraras brigittae.
