Things that are best left in the ocean

[SeahorseKeeper]

I'm interested in finding out what are some inhabitants that we see for sale that should not be housed in an aquarium.

I'll start: linkia starfish. It is rare to see them thrive in the home aquarium.

Sharks and octopus

I like linkias and there are people that can get them to thrive, just with larger tanks sometimes

Christmas tree worm rocks are my favorite animals but prob one of the hardest species to keep thriving long term.

Also Crinoidea species are sometimes sold but only a few people have successfully kept one alive for more than a couple years.

I've been guilty of both.

chamber nautilus should never be in a reef tank

I had a blue linkia as my 2nd invertebrate and it thrived, until it and my anemone both got themselves in trouble killing each other :s and it had a baby. that was my first marine tank!!!

I know this is the beginner forum but sharks and stingrays can be kept successfully and happily with the right tank. We are talking tanks of a few hundred gallons and really good filtration

but to clarify they are not for beginners

sand sifting stars, they will eventually die unless you have a huge tank.
scallops, they will die too.
Non PS Gorgs - unless you are some kind of wizard, good luck.

Mine is fat and thriving after 5 or more years. I know they do not normally survive, but mine has taken to my DIY fish diet.

Come check out my tank. I have 3 thriving munching on the plethora of sponge within my live rock. They love the yellow and pink sponges. However with that said, you need a well established tank for them with enough sponge for them to eat.

If I was to list some out, I would have to say Ribbon Eels, Mandarin Goby (guilty) and Sea Apples just to name a few. There are other ones but my brain hasn't had it's coffee yet this AM.

I've been in the hobby for a while and I know that they can be kept, however to properly care for them you would need a huge tank. You would need a tank much larger than any standard tank. The biggest standard tank I can think of is a 240. For a 4 foot bamboo shark 8 feet long is not enough swimming room. And 2 feet is not enough room to turn around. The smallest tank I'd reckoned for a shark would be a tank at least 12 feet long and 5 feet wide. Which of course would need insane filtration. As for a stingray I would do no less then 9 feet long and four feet wide.

Just to correct your post, bamboo sharks will only reach 41" in length which as we both said is too large for any "standard tank. that 7" is a big difference lol
I have known a few people who have used huge rubbermaid stock tubs to keep sharks and rays and it has been plenty of room. especially for the carpet shark species which dont tend to swim that often.

i myself am guilty of keeping a full grown bamboo in a standard 6' 220. i tried to give him a better home than the 125 he was in. and i knew my tank was way too small. i lost him about 6 months later when he managed to push the lids off and jump out. It still kills me to see bamboo eggs in any of the local stores.
here is a pic of the one i had

I agree that they can be kept. Just not full life in a standard tank. And a rubber made tub is obviously not a standard tank. I've always dreamed of buying an above ground pool just for sharks and rays. And yes you are correct on 41 Inches. Sorry.

Carnation Corals, I see these in LFS all the time and they really shouldn't be brought in to the hobby, minus severe experts. Unfortunately their color attracts many in this hobby and people "try" them anyway.

There is an article in TFH this month that touches on this point.
Moorish idols, parrot fish, rock beauty, mandarins, pacific blue tang, regal angels, multibar angels, powder blue tangs, leopard wrasse, purple queen anthias, and hooded butterfly fish....from the article. Just quoting he article here...not my list
