Been having a problem with the brain. When I put the last goby in I'm thinking he got sand inside the brain. It has been defated for about 3 weeks now. It's not receeding or bleaching. It opens up at night and eats just fine. It's just not swelling up during the day. If there is sand in it, will the brain take care of it or do I have to dip it in something?
