List of fish/inverts that hobbiests should avoid

I would just clarify:
Linckia and Fromia stars need huge amounts of LR...sand sifters, Archaster, in fact, need the opposite - huge surface area of open sand.
I would add:
Crinoid (Feather Stars) - nearly impossible to keep in most systems; most will die within months. Acclimation is critical, be feeding them is virtually impossible for most hobbyists.
Basketstars - Like their relatives, acclimation is critical. This animal needs hands on daily feedings and is nocturnal. You will have lots of late nights if you intend to keep it, but generally they will starve. If successful, the animal will outgrow most tanks. Sadly, few get the attention then need.
Can't remember if it was added:
The orange spotted filefish - a showy and beautiful fish, but doomed in most systems as it is an obligate feeder on SPS coral polyps.
An excellent idea for a thread

WHY arrow crabs? may I ask? Just want to know your opinion?

Arrow crabs eat snails, feather dusters, smaller inverts, and when they get larger, can even eat small fish. They are not something I would want in my aquarium, however, they are still able to be kept in captivity in the right system.
Dragonettes are another fish that are very keepable in the right conditions. Many things just come down to researching before making a purhcase and ensuring that you have the right tank specifications, water quality, and tank mates to go along with whatever you are looking to buy.
Ophiura, thank you for the clarification about the starfish, and the inclusion with the feather stars. I totally forgot about them because I have only seen them for sale a few times.

Can anyone think of the Wrong names that some of these critters are called. I know I've read posts where the poster says, "But the LFS said it's a ______ not a ______." I can't think of any off hand, but then I'm a relative Newby.

How about Conchs, Cucumbers, Nudibranchs, and Urchins. Are these easy to keep and are they recommended for a new tank?

Awesome thread Lion!!!
I would like to add that pipefish should only be kept with WILD CAUGHT seahorses. If you introduce the pipefish to a tank with captive bred seahorses you run the risk of introducing parasites that the CB seahorses have never had before.

No, I would not call them "easy." Cucumbers, nudibranchs and urchins are definitely not for new tanks, and water parameters must be very good (esp specific gravity). Acclimation is critical. I would not consider any until the tank is at least 6 months old.
Cucumbers come in two types - filter feeders and sand sifters. Both have the potential to crash a tank and kill fish if they die. The colorful filter feeders such as sea apples are the greatest risk in terms of toxicity. These animals need to be fed specific diets of small particle sizes. Sand sifters need specific particle size substrate as they ingest it.
Urchins can be bulldozers of rock work and frags. Some are threats to soft corals, and other grow huge and have long venemous spines. They may eat coralline algae and this can be an issue for some people.
Nudibranchs are very very delicate in general, and often have very specific diets that are not met in our tanks.

Thank you Lioncrazz. I'm getting ready to set up another 150G tank and my wife really wants a dwarf lion for the tank. I showed her this post and now she isn't so sure about getting one. This thread is a really valuable tool for the newcomers to saltwater fish. :thinking:

How about red starry hermits...they munch on alot of things. I caught mine eating the orange linkia so now its in the qt until I have the second tank set up and figure out which tank I will put him in.

Alyssia, Ophiura, thank you very much for your contributions!
Leftybite, I am glad I could help. If she wants a dwarf lion, I strongly recommend the fuzzy dwarf. This species usually ships VERY well, and is SUCH a personable fish. My fuzzy dwarf comes to the front of my tank when she hears me talking to her. She still feeds so calmly and peacefully right out of my hand (2.5 years later and fully grown).
Slesia, while I do agree that starry hermits are something that I would never put in my tank, people with triggers, groupers, etc. can make good use out of them usually.

I bow to your wisdom Ophiura.
My Carribbean cucumber has never been a problem, and my slate pencil urchin snuck in on some Caribbean rock and has grown fantastically.
Clearly I spoke without researching enough as I shouldn't go with personal experience as the only source of knowledge.
I think any "sand sifting" creature needs to be on the list as well.

Hey Lion
Definitely add a mandarin (spotted) goby. I didn't see it on the list and it's well known if they don't have alot of LR and pods to feast on, eventually that fish a person grows attached to for it's color and beauty will starve and die.

Yep, I will add the mandarin. Since I can no longer edit my first post, I will just allow this thread to keep going with suggestions, and then when it is all said and done, I will compile one huge list of everyone's suggestions, as well as all of my own, and then submit it so that it can be archived. That way, there will be one huge list in the archives, and this running list on the new aquarists board so that they can read different comments back and forth about the species we are talking about.
Please keep the suggestions and comments coming. With the amount of input everyone has given to this thread, I am sure this thread can be a great help to anyone looking adding a fish to their aquarium.

I think sand sifting cukes are okay as long as they are in a big enough tank.

Don't forget the always talked about Mandarins, Phycodelic or Blue, inexpensive but hard to feed if not a large established tank with live rock for lots of co-pods.
