Sea urchins....

[SpareParts]

Are there any aggressives that will not eat sea urchins? I have a 75 gallon tank dedicated to urchins (12+ unique species) and would like to put a single agressive species in it. I know most triggers will eat urchins, how about a dwarf lion or a blue line grouper? Or maybe even some kind of Angelfish?

I have a flame angel and blue throat trigger with one and they look at him and move on

I have had urchins with most of my lions and they just ignore each other.

You should post pictures of your set up. I have a couple different kinds of urchins and think they're pretty cool.

My puffer, yellow tang and lion pay my urchins no attention.

Maybe a Yellow Soapfish Diploprion bifasciatum would a fine addition ... odd shape and nice color ... and not so big predator...

A marine betta is an option

That's a big fish for a 75g tank!

IMO a betta is also too large for a 75.

Most triggers, groupers, tangs and angels will outgrow a 75. A Dwarf angel or one of the smaller lionfish species would work.

Here's a few images of my system:

I ended up putting a cometfish, squirrelfish and red talied filefish into the system So far, everybody gets along well.
