Welcome!Relatively new to marine fish keeping.
I have a Fluval Flex 15 currently with a black and white OCC Clown (Stanley), Orchid Dotty back (Prince), couple blue leg hermits, six turbo snails, cleaner shrimp (unnamed as of yet).
Green mushroom, red mushrooms, Orange Florida mushroom, Kenya tree, some sort of zoa's, pulsing Xenia, GSP, pale red Monti and most recent addition two head Green purple tip hammer coral.
Bought the tank used with the Kessil 160 Tuna light. I've been running this setup for about 6 months. Still learning and researching. I've tried to keep a couple different BTA's red and green but no success, unfortunately.
I have decided that I will upgrade to a larger tank, maybe the freshwater 55 may become a marine tank but Iam not sure. All I know is that retirement is off the table now, lol!!!
