Wanting to do a Betta Sorority but I really don’t know how many I could have in my 40g Breeder. Recently just tour it down because my ex-roommate decided to dump Gain detergent in it. Tour it down, cleaned everything and now it is just running with water in it. Going to do a full water change and clean everything again to make sure there is zero residue inside anything. It’s going to be heavily planted with a piece of giant driftwood in the center and BDBS about 3-4” deep. I have a heater, light, filter and etc. I will be fishless cycling it once I feel comfortable doing so. Anything that alarms anybody?
