Do clown fish ever sleep?

Yeah they don't really "sleep", but my clowns go to their corner of the tank where there's the least amount of float and just bob up and down there. Slower "fluttery" movements, just to keep them in the same spot. Precision station keeping sleep style.

 

Some will say wait at least a year, mostly I believe because of nitrate fluctuations and so on. Both of my tanks got a seabe after about three months. One tank is almost a year old with original seabe, the other tank is newer and the seabe has been there for about a month and is doing great.

Just make sure you read up on which anemone you are planning on buying THOROUGHLY before buying!!

If you read about seabe's enough you will find that people say they don't live long and usually die within a few months, I chose to get them anyways but also have been very vigiliant when it comes to their care and needs.
