Not necessarily overstocked but too busy with 5 schools of fish inhabiting the same area of the tank. I probably would do 2-3 schools of mid swimmers with cories and a centerpiece fish. Larger schools of fish usually have more natural behavior.
I get that reaction a lot. The tank was set up in January 2016 and they were all supposed to be baby girls. Some turned out to be male and I didn't feel a need to separate them. Still dont. Its not necessarily a stocking I would recommend but its working for me.
With something like that it will be trial and error. Depending on how much you feed it may need cleaned any were from every 2 weeks to a month. You should notice a difference in color or bubble flow that may give you some idea.
I have 3 males and 16 females with glowlight tetras and cories in a 75 gallon tank. So far in 2 years I have had 1 baby born in my tank. Has anyone had any success breeding them in a community tank? I know I can set up another tank but that's not as cool. Any suggestions to up my chances?
