Got his guy yesterday so I get that he’s still very stressed. he’s in a 20g Barebottom QT tank w no live rock. There are a few pipes to hide in and some plastic plants to offer shelter. Back and sides of tank are covered. He’s stuck here for 3 weeks. He’s constantly swimming upright in this one area. Suspected swim bladder issues but he’s fine at lights out and swims away to sleep. He’s clearly stressed and looking for a way out. Is there anything I can do to help him feel comfortable in this unnatural and strange new temporary environment? He’s huge and I’m afraid the tank is just too small for him
