Don't Keep

The Moorish Idol is a gorgeous fish by any standards and a very desirable one for any aquarium, or is it? Moorish Idols have a very specialised diet and nothing else is able to replace it. The result - 90 % of captive specimens die within a few months of being caught. None live their natural lifespan in captivity, they should be left where they are. There is an alternative in the Bannerfish, which if given proper care will adapt very well to captivity and is almost identical to the Moorish Idol, which makes it even more pointless trying to keep a Moorish Idol.

A Bannerfish will live for many years in good health in a well cared-for aquarium, whilst a Moorish Idol will die of starvation within a few months, however well cared for.

There are other fish which do equally badly in captivity and almost always die prematurely. But despite this quite a few of them are commonly seen for sale in fish shops. By buying them you are actively encouraging the trade to continue, if they die in the dealer's tanks he will be reluctant to replace them. In other words they won't catch what they can't sell.

- Shrimpfish (or Razorfish), Aeoliscus strigatus.
- Bandit Angelfish, Apolemichthys arcuatus.
- Multi-barred Angelfish, Centropyge multifasciatus.
- Foureye Butterflyfish, Chaetodon capistratus.
- Lined Butterflyfish, Chaetodon lineolatus.
- Ornate Butterflyfish, Chaetodon ornatissimus.
- Long-nosed Filefish, Microlabrichthys evansi.
- Blue Ribbon Eel, Rhinomuraena amboinensis.
- Nudibranchs - specialized feeders, when dead can highly pollute tanks.
-Carnation Corals - deep sea coral that requires darkness and lots of feeding.
- Octopus - require highly specialized environment to prevent them from escaping.
- Jellyfish - require a round tank with good water flow to keep them moving as they have minimal ability to propel themselves
- Cuttlefish - highly specialized fish that only live a couple weeks in professional care
- Flame Scallops - not enough is known about them and they require large quantities of zooplankton for feeding, generally unattainable in an aquarium.
- Most Sea Anemones, which generally only live for 1/80th of their possible lifespan when in captivity.
- Mandarin Fish - need a large mature tank with a natural food supply or they will die.

The choice is yours!

Maybe you guys with experiences with these animals can chime in. Or if there are other fish that should not be kept in a fish tank please let us know. Thanks

I got a snail that was from a tidal zone, they didn't know what it was at the LFS (told me turbo) and that thing has been escaping ever since. It is trying to get to the shore and wait for the tide I guess, but all I know is that I have found it on the rim several times, behind the stand twice and once on top of my glass cover baking directly under my lights. Each time I just plop it back in the tank and a few minutes later it is cruising around. I'm curious where it is now, I haven't seen it for a few weeks; maybe it will turn up when I move around my chemicals and equipment in my stand.

I've had my Clown tang for almost a year now. He is fine and definitely Not the most aggressive fish in my tank :fish:

i have heard about a lot of success stories and even breeding of Dragonets. 75g would probably be the minimum for these fish and that isn't that HUGE! Must be a mature tank with a knowledgeable reefer.

I am currently at about a month with 1 female, and have just introduced the male and they are already showing courtship behaviors.

I wonder what they mean by Most Sea Anemones? Does that mean BTA's or other Aquarium kept Anemones?

I've seen jellyfish in an aquarium at Phoenix Mall. Really, really, really awesome. How often do private reefers keep them? I see they need to be in a round tank. If you have a round tank dedicated to them, are they reasonably easy to keep?

I guess I am lucky I have had mine for about 6 months now and eats what ever I throw into the tank on top of cleaning the inhabitants.
mine is the same way, he is a champ and eats whatever I feed. And he is a trooper at cleaning the other fish
