Attached are photos of gelatinous blob found in tank this morning. Sitting on top of some Feather Caleurpa (might not be spelling that right but the green seaweed) there is this white blob, about half an inch or two centimetres in diameter. Tank is FOWLR, emerald crabs, starfish and astrea snails for cleanup, and two blizzard clowns, a lawnmower Blenny, and a Longnose Butterfly fish. Tank is 120 gallons, including the 30 gallon sump in that. Tank is also four to six years old by now (somewhat forget when I got into all this) but is well established and I usually don’t have anything show up in the tank that I don’t know the origin of. Just upgraded lights last week to 2X Radion LED disks which have dramatically increased the amount of algae just on the glass etc, wondering if that could be related? Let me know if anybody knows what the heck this little white blob is thanks in advance!
