Mantis shrimp algea like growth on back

[Tom.suurd]

So ive gotten what i think was a male shrimp about a week ago.
Since i got it ive noticed this weird algae like growth on its back.
Does anybody know anything about this, is it bad, can i do anything about it.
Its eating just fine.
Its in a 110 liter aquarium.
I can't really take a good picture of it but here is my best attempt.

Could we get a picture without the blue light?

So it looks mostly exterior to me. And since mantis shrimp molt, I'd be willing to bet that the algae-like stuff on the shell will come off too. But I'm not a mantis expert, so take my advice with a grain of salt.

Unrelated to the algae issue, but those spots on the back look like possible shell rot? I’d do some research on that and see if that’s affecting the shrimp as well, shell rot is super common in peacocks. I found a good source about it on a different forum from several years ago but I can’t remember the name if I can find it and figure out how to link it here I will

Shell Rot & Peacock Mantis Shrimp (O.scyllarus)

G'day all I hope this clears up any questions about Shell Rot & O.scyllarus, effectively it is a compilation of responses from Dr.Caldwell to many others (including myself) rolled in to 1 piece I separated it into 3 major areas that seem to be to of the most major concerns...Lighting, Housing &...

Ive read the article about the shell disease but i coundt really quite catch what the solution was and what they meant with "cool lighting"
Do you happen to know what he means by that
And did you succeed in curing shell disease and if so what did work

I haven’t kept a mantis (yet) so I don’t have personal experience, I found that doing research preparing for my own. My takeaway was soft lighting rather than really intense and cooler toned lighting (soft blues?) I’m not even sure if I’ll be putting a light on my tank at all, at least at first. My tank will be next to a few freshwater tanks and will receive indirect sunlight, so that’ll probably be enough for viewing. I may eventually get a cheaper light to grow soft corals like Zoas but I’m worried about the light bugging the mantis. Past threads on here found that the mantis was much more outgoing without the extra light.

As for the algae growth, it could be just that: algae. If so, I would think that it will come off with the next molt, and could be a lighting issue? I’m really not sure. I have yet to keep a saltwater tank (I will soon ) but as far as freshwater goes, algae happens with an imbalance of lighting and nutrients, and so far it seems a similar thing in saltwater. What are your parameters?

So that would mean lights towards like the purple shade?

 

[FreshwaterConvert]

I think more blues and less purples and reds and yellows, but also just less intense in general? I’m still really new to the whole lighting thing in general in marine setups. What light do you have and what intensity’s do you have it at?

I dont really have a way to messure that,
I just changed it to a very dim purple
Its a lot dimmer than it seems on the pic
