Hittade lite på wetwebmedia: Funky Lionfish behaviour 12/6/06 Hi everyone, <Anthony> You were kind enough to help me out a couple of months ago with a Blue-cheek Trigger problem, so I figured I'd pick your brains a little more. I've looked through google and your Lionfish section for something resembling this, but have found nothing. I have a (I believe) 10" Volitans in a 180 gallon tank with a few friends that have been around for a long time. Nothing has changed in the tank prior to this behaviour starting. What the Lion is doing is swimming around with his head above the water surface. <Not good...> Eyes, mouth... it's as if he thinks he's a crocodile or something. He's bumping into things, and is going into his second eek of being on a hunger strike. I did read something about a lack of aeration for other behavioural issues, <Yes... best first guess> and was wondering if him having his mouth above the surface is a means for him getting air? <This is a/the theory> Someone told me that it's a bad idea to connect the air-intakes to the powerheads. Can you confirm that? <Not an issue... very small bubbles are problematical, not ones larger than say 1 mm in diameter> I have 4 powerheads being controlled by a Wavemaker Pro in the tank, with plenty of live rock, excellent filtration and decent water conditions: 78 degrees, 1.025 SG, 8.2 pH, 0 ammonia, 0 nitrites, 5 ppm nitrates. I tried dropping some ghost shrimp in the tank to get him to eat, but got no response. His color & body look good. He's just acting like a freak. Thanks, Anthony <There are other probable causes for the observed behavior... next in line might be that this fish has "swallowed something"... like gravel, a hermit crab... and is suffering duress consequently... I would try adding a dose of Epsom Salt (see WWM re) and keep offering foods that this fish is known to accept... daily. Bob Fenner> Någon som varit med om något liknande?
