Today I have come to inform you all about the benefits of a sea hare. To start things off, I have had a problem with GHA (green hair algae) for the past 5 months. I looked into all sorts of hair algae eaters such as different inverts and fish. I looked into all sorts of tangs and blennies and crabs and snails and everything out there before concluding with a sea hare. I was a little weary because of the price ($30) because of all the tangs and such that cost around $100-$200. I talked to fellow reefers at some stores in Denver and they mostly recommended a sea hare or turbo snails. Upon buying the hare it went after the algae immediately and I could see the effects soon after. Now 1 1/2 weeks with this little invert in my tank I am sure to say that it is a 10/10 recommendation for anyone. There is only one con to this animal. Mine does not like to get up on one of my rocks. But as we are all reefers, we know that every animal is different and other sea hares might not be like this. I might do some before/after photos soon so that you all can see the difference it made. They are good creatures and I would recommend them to anyone with green hair algae in a heartbeat.
