Hello everyone, I'm a newcomer here! Allow me to introduce you to my 20-gallon long reef aquarium, assembled on a budget by carefully selecting items on sale. I'm eagerly anticipating the moment when I can begin introducing various corals to enhance its beauty. Please pardon the presence of a divider; it's currently in place because one fish on the left side had been quite aggressive towards the one on the right. I've spent a lot of effort nursing the bullied fish back to health over the course of a week, rescuing it from a state where it was gasping for air in a corner. I'm still unsure about the future of the divider in my setup – it's an ongoing decision!
