SarahJ Posted June 26, 2021 Share Posted June 26, 2021 As the title says, can anyone identify what this thing is please? I originally thought it was something just stuck on the glass, but I’ve been watching closely today and it moves…. there is also a bubble type thing over his right shoulder….good or bad? Thank you! I am loving all the things that keep popping up, I’m spending hours on end just watching. sarah  edited to add he isn’t that big, about 3mm It moves like a snail? The bottom is where the two leg bits are and lifts what looks like the head, off the glass to have a look around Quote Link to comment
Jungle_vip Posted June 26, 2021 Share Posted June 26, 2021 Red planarian flatworm. Relatively harmless but can become a pest rather quickly. Will cover corals and cause bleaching. Can also be an issue if you have a major die off from the toxins released. Quote Link to comment
Jungle_vip Posted June 26, 2021 Share Posted June 26, 2021 I’d suggest removing them through siphoning with an airline tube to keep them in check. Some Fish may or may not eat them such as a sixline wrasse. Chemical treatment is an option if need be but would not be my method of choice. 1 Quote Link to comment
