I love mine. They took a good 5 days or more to come around after adding them to the tank. They were very timid and spent a lot of time hiding.
They also weren't eating unless food floated down to them. After the first 5 days or so they really came around and now they are the most social fish in my tank. They great me every morning, they hang out with my Sunset gourami all the time.
At night they sit on the bottom in my plant cover and sleep. It's hard when I have a pregnant one because I've missed 2 batches of fry that were born over night because I miss took her hiding as sleeping at night.
They love peas and carrots too and often nibble on the algae growth around my tank
