from my knowledge yes they are schooling fish and they prefer tanks with plants. they dont grow to big averageing 2-3 inchs only. i personally never kept them in my tanks but i do have a uncle with 8 of them in a 29g planted
glows are lovely fish! The females get quite a bit larger than the males. I prefer them over neons actually. My problem is that I can't seem to get any young healthy ones from any of the stores in my town.
