I'm very concerned about the beautiful blue Betta I bought my son Aaron in July '07 for his birthday. We have kept it in a clean tank with a a plant we grew from bulbs that said they were indigenous to its region. We have been feeding it just a little of the food it said was its normal food in the wild (possibly blood worms?). The tank has a filter/oxygen tube. I've done everything I know how to do.
It went to our neighbor's house over Thanksgiving and came back sluggish. (It got a little sluggish when it got colder outside, too.)
It doesn't seem interested in eating. It floats crooked or almost on its side (but it's alive). What do you think is going on? Is there anything we can do?
