Look at this: http/www.petfish.net/articles/Fishy_Fun_...les/tidbits.php, it has some very cool tidbits like: all shrimps are born male but they turn female, its against the law to have a pet in Iceland, most saltwater fish would live fine in a tank filled with human blood, some carps live to be 400 years old, and more!

Wow, that is neat. Great find CR!

Years ago I saw a test area at the Shedd aquarium where they were evaluating different types of tank filtration. The test was in 10 or 20 gallon tanks and they were evaluating under gravel, canister, box and outside power filters. I was told that the under gravel filtration beat the rest hands down.

They don't have that anymore. I went last year. They are doing some pH experiment thing last time I went.

Pretty interesting stuff.

There are some outrageous sounding things on there that I'd agree are probably true....like the comments about carp/goldfish.

There's a 120 yr old goldfish (which are carp) in Japan, and goldfish really do need light, mostly sunlight or flourescent but any kind of light is better than nothing for them. Their colors will wash out big time and they will fade big time and be very despressed without light. I can see one turning white in a room absent of light over time.

There are a couple things in there though that aren't 100% correct;

"Scientist have developed glow in the dark zebra danios - using jellyfish DNA."

It was actually the DNA of a sea anemone (Nemo's home).

"Dolphins don't automatically breath; they have to tell themselves to do it."

I've seen video footage of a dolphin drowning while trapped in a net made for catching tuna. It was to the point of going into convulsions from not being able to escape to the surface and breathe in air. I don't think it was going into convulsions from having to remind itself to do it.
