urchins

[mr. bojangsjang]

are there any carnivorus/scavenger species of urchins? I am setting up a seagrass tank with seagrass and macros and I would love a urchin but all the species that I know of will destroy seagrass and macros. Any suggestions?

There are omnivorous urchins but for the most part I think nearly all will consume seagrasses. Ideally, this wouldn't be a risk if your grass is doing well. In theory macros and seagrass will outgrow the pace of the urchins consumption.

For the most part urchins are lawn mowers
