What plants are best for a SMALL 1 betta fish bowl?
Ugh, when you say “small” with “betta” and “bowl”, you’re guaranteeing someone to berate you to death on animal cruelty. I won’t even touch that remark, but I will state my opinion. If you have access to sunlight, then a bulb or the like will do fine. Almost anything will. The drastic change in an unheated bowl is not too healthy, though, but if you have a heater in there anyway that maintains a certain temperature, then no worries. In this case, I’m doubtful if that is if it really is so small. Try water sprite. It’s effortless, your betta will play in it and love it.
