Hey all! So I recently decided to go against getting a frogfish due to having to feed it live… I have a 21 gallon rimless cube. It’s a weird lagoon style tank. I think it’s 20x20 or close to that. I want to do a species only tank… but I would love to hear what ideas y’all have because I’m so indecisive lol. I’m up for any challenge! Would prefer to stay away from cephalopods and eels as I do not have a lid for the tank. Thanks!!
