sorry its been awhile but its hard to be really into this hobby with a idle tank. well after losing all my fish to what i believe to be a parasite of some kind. i let my tank sit fish free for alittle over two months to let the parasite run its reproductive cycle and now i added my first fish. a flame angel that was in a friends tank for 1 1/2 yrs. this is just to see if my tank is ok because i know this fish is healthy. if it dies then i have no idea what to do next. the whole time my tank was sitting without fish i still had 3 corals an alot of snails and crabs so my water quality is fine or they would have died off right?
