since this is a lion fish topic..I might just as well post my question here instead of starting another one....

when a lion fish sit and rest, sometimes it's body colour turn dark...does it mean it is not happy?

how about having a "slight" cloudy eye? is that a sign of a fluke of some sort?

You may appreciate the information on lionfish in this link:

Good luck. Keep an eye on it.

lions must be very hardy.....I was lucky that my fault didn't kill it straight away....anyway..on my way to fix the thing up...daily water test, water change if needed and add bacteria addictives

I would guess it was ammonia burn. You spiked ammonia, and it was converted to nitrites.

in fact I changed half of the filter media in my canister filter, did a water test just then and realise there is nitrite present....I guess this is the cause...

Couldy eyes are a problem. Did you make any changes to the tank such as adding a lot of live rock, r something that would have caused a cycle?

As far as its body changing color, I believe that is merely for hunting purposes. When they prop themselves like that, I belive they are generally waiting for prey to pass by. They are ambush hunters, so blending in is essential.

i am thinking of my sw tank 2-be and i was wondering the dangers in haveing lion fishes. i was watching the posion show, and lion fishes were on it. i would like to get some, but not if they are real dangerous.

They can live with other fish, but they need to be larger then they can eat. Putting a volitan with a royal gramma woudl be a bad idea. Putting a volital with a maroon clown, would be fine if the clown is large enough.

If you get stung, yes, warm water will help ease the pain.

a couple more questions. i see them in public aquariums with other fishes, in nature don't they kill fishes like that, so will it co-live with other sw fishes. also i heard if u get stung then put ur hand or arm in hot water. but it will still hurt for a few days. is this true.

You made the comment that you might like to keep some...to my knowledge, you would need an extremely large tank to hold more than one...

Depends on the species you want. In actuality, some Lionfish actually exhibit teamwork in predatory nature when kept together, so some species don't have problems with each other's company (unless there's such a significant size difference one can be considered another's prey). Also, some Lionfish are smaller and can be kept in smaller tanks as well, although it is in fact the smaller ones that are more territorial and shouldn't be kept together. In a good sized tank you could keep multiple of the medium-sized lionfish, such as Radiata and Antennata. In a colossus of a tank you can study the aforementioned teamwork among Volitans. If the tank is about 30-55 gallons, a single Dwarf Lion may be appropriate.

Yes, I did my research, but I still don't have Lions to show for it.:%)

The aquarist is one who must learn the ways of the biologist, the chemist, and the veterinarian.

just always make sure you take your hand out of the tank if you see it coming..and of course don't put your hand in close to where it is for the start...then virtually they are safe to keep with no harm

PM/email/msg me if you have any questions/comments regarding me or my knowledge or if you want me to read a thread.

Lion venom can cause cardiac arrest, stroke, paralysis, and many other things. The main thing to remember is to be sure of where they are at when you are in the tank.

Lionfish are venomous, but their stings aren't often fatal. The most severe reactions occur in people who are allergic to the venom, in which case a trip to the hospital may be necessary. This is pretty much the same as with normal honeybees. Most people can take a sting with little trouble, but those who are allergic to the venom need special attention.

This is the same as with some of the other venomous saltwater fish, such as the stonefish. The toxicity of the venom may vary, but few people die from them.

Lionfish are pretty widely sold, my work has had several in the past month. They probably would not be legal if they were that dangerous, or folks would at least need a special license to own them. Just be careful when you are working in a tank with lionfish, just as if you owned piranha. If you are vigilant, the chance of an incident is low.

They are not that bad. It's kind of like a bee sting. It hurts, and can get infected. The main thing is to watch what you are doing. Always keep one eye on your hand, and the other on the lion. They will not come after you. Most stings come from bumping in to them, or cornering them and causing them to panic.
