Help on a new 55

[crazyaqua]

I have a small long spine urchin in my 37 that is being moved to my 55. My question is i want to look into making it an aggresive tank but dont aggressive fish general eat urchins and shrimp. I love my urchin and i dont want him to become a snack.

Thanks

depends on the fish. Just check. What fish are you looking at? If you keep the fish fell feed they be less likely to eat the urchin, but you never know. Just keep him in your 37

I was reading the long spine urchins get big but if he will be ok in 37 i guess i can leave him in there. Thanks Sin
