Appreciate that advice! One Severum is better than none severum! Will consider that while finishing my stock plan.One severum with the loaches sounds better to me. It removes the risk of them going ham on each other or going to town on other fish if they breed. Also less water changes
Also on clown loaches, there are others such as yoyos which have all the fun at a much smaller final size! If you do take clowns there are plenty of people who'd take them when they outgrow your tank, often fetching an okay price too. So there should be options for you
Welcome aboard!
