I have FINALLY come to terms with a good lighting system that will provide more then enough viewing for me and shouldn't be to bright for the stomatopods themselves hence risking shell rot, at the same time I believe I can keep some corals with these lights albeit only the most hardy...Ricordeas/Mushrooms, Disc Anemones, Star Polyps, Sea Mats, Button Polyps/Zoanthids & Leathers.
The Lighting is LED made by HATO one must remember that these are mantis shrimp tanks NOT reef tanks therefor lighting doesn't (and shouldn't for the sake of the mantis shrimps health be that bright (I'll generalize it for the sake of the more prone to shell rot species and accommodate for them when it comes to all the tanks lighting).
There quite cheap setups and I am happy with the one I currently have on my nano (nano also has a DUAL T5 fixture too tho..) however I have done the comparison between the 2 and this new LED that is $60 cheaper then my T5's and never needs to replace bulbs is a LOT brighter then the T5 even though it is a lot less wattage.
STAND A e.a. tank gets 1x600mm LED Fixture which pumps out 18watts e.a.
STAND B e.a. tank gets 1x900mm LED Fixture which pumps out 28watts e.a.
STAND C e.a. tank gets 1x1200mm LED Fixture which pumps out 37watts e.a.
I just hope that they pump out enough wattage for some at the very least HARDY corals else I might have to either....
a) - Double up on each tank so, 36watts e.a. tank on stand A, 56watts e.a. tank on stand B & 74watts e.a. tank on stand C even then though I just don't understand what corals need with lighting so tend to go for the hardiest and just over compensate knowing that through there hardiness they'll be fine (cough cough zoanthids).
b) - Rethink lighting yet again -_- my 2 main concerns are (1) Wanting to keep some hardy corals like Ricordeas/Mushrooms, Disc Anemones, Star Polyps, Sea Mats, Button Polyps/Zoanthids & Leathers obviously not all in one tank but 2-3 dif in each tank. (2) Not wanting to go to bright with the lighting and risk either making the mantis more reclusive or just creating shell rot problems.
