You really need a bigger tank for the fish you have. Can you get a job? Earn a few hundred dollars or so, and buy a 55 (or larger; the bigger the better
) The weight is absolutely not a problem. I have a 75 in my room. For dithers in a 29 gallon, maybe small danios? Most of the popular ones are too big for that tank, like giant danios. They need a larger tank. Right now, you have several convicts, a JD, bichir, and more in a 29 gallon tank? Correct?
Your tank is looking great, you just need to sort out the stocking issues.
