After doing months of research and spending lots of money I set up my very first saltwater tank. I used KPA live rock so I could get all the good that comes with it. Well I did not think enough about the bad. Fast forward a couple weeks and I purchased my first fish, 'Boo', an exquisite firefish. We named him Boo because he loved to play peek-a-boo, he was a skittish little thing but absolutely beautiful. Well this morning I woke up and he was laying on his side outside of his cave. I go out and come back a couple hrs later and he's upside down so I immediatlety pick him up with a net just to find a massive isopod latched right behind his fin. Of course with my carelessness once I got the isopod off it got back into my system. Well the firefish couldn't recover and passed away a few hours later. **** isopod. I don't even know what to do from here, this has been my dream and I've put so much work, time, and money into it. I don't want to take it all apart because I do have some corals that I like but I can't have a tank without fish, I love the action and personality they bring. Been a rough day Only had him for 4 days and he was in perfect condition until this morning.
