SURF2 and SURF2

[Floyd R Turbo]

Seems like this would work if you had all herbivores or at least omnivores. Outside of that, I think any fish will eat whatever is edible if it gets hungry enough...doesn't mean they will thrive!

When srusso did his freshwater livebearer UAS he never had to clean the screen, similar principle, but again herbi/omnivores only

[RkyRickstr]

Maybe he means he is not feeding the coral

[Devs]

Where's he gone, we need questions answered

[SantaMonica]

Diffractors, not lenses.

No carnivours.

[Devs]

Are those the same things as diffusers ?

[SantaMonica]

Similar.

Are there such things as herbivores in a marine setting? At least a few % of tangs diet are the meaties that live on the algae.

Of course there are.... they just don't come in fish form. One of the most popular herbivores I can think of off the top of my head is a lettuce nudibranch.

[Garf]

So they don't consume any meat ish stuff, whatsoever ?

I can't say with 100% certainty, but I can't find any info on them eating any type of meat. The opposite actually, they require algae to live.

The Lettuce Nudibranch is a very interesting and useful creature. It helps tackling the unnecessary growth of algae. The Lettuce Nudibranch is photosynthetic in nature, and gets benefits from the chloroplast in their tissue from the algae they eat. It sucks in the chlorophyll contents of algae, and then incorporates that chlorophyll into their own tissues. It belongs to the family Elysiidae. The Lettuce Nudibranch is closely reassembled to a lettuce leaf, which is why it is named the Lettuce Nudibranch. It reaches a maximum size of 3 inch and is very hardy. The Lettuce Nudibranch is passive in nature, and is more active during day time and less at night time. There are no distinctive features that differentiates male from, female. The reef tank should be maintained with 70-80 degrees Fahrenheit for the proper growth and development of the Lettuce Nudibranch. It is a bright green color with ruffles across its back. It has an elongated oval shaped body and due to presence of ruffles it increases its surface area in order to absorb more oxygen for respiration. The Lettuce Nudibranch destroys and eliminates the growth of algae by foraging on live rocks and aquarium glass. Thus, it helps keeping the environment clean and clear. It is non venomous and a very hardy species, which makes it a terrific addition to any reef tanks. The aquarium needs to have some live rocks which serve as a natural shelter for the Lettuce Nudibranch. They belong to Gastropods class who are snail like creature and do not possess any shell for their protection. The Lettuce Nudibranch is very peace loving and gets along with other inhabitants. It surely makes the aquarium more attractive with its interesting appearance and function.

As the name suggests, Lettuce Nudibranch - Bryopsis - Eating Nudibranch feeds exclusively upon Bryopsis Algae and is therefore, Herbivorous in its feeding habit.
