Why do people who keep fish on display in their houses find it necessary to constantly run a bright light?
Posted on Sep 11, 2008 under fish habitat | 7 CommentsYet, when the fishes are in their natural habitat and swimming wild and free, they have little or no light.
Actually many fish come from very light environments. The sun will penetrate 10-15 feet in even "dirty" water and provide plenty of light.
Many of the species that are kept in an aquarium come from waters only 2-10 feet deep and would typically get a lot of light through out the day.
But the REASON we have lights is because we want to be able to see the fish in the tank. Without lighting in the tank it would be next to impossible to see most fish, and then why bother having them?

¡ At last we found them!
Moenkhausia pittieri “diamond tetras” in their natural habitat! For 3 years I tried to film these small Characiformes in their natural habitat with no success for they are partially extinct in their wild form.

which of these is a reasonable source of energy for producers in this habitat?
Posted on Sep 10, 2008 under fish habitat | 3 CommentsIn recent years, marine biologists and engineers have joined forces to explore the deepest parts of the ocean in submersibles. Unusual creatures have been discovered living at theses depths near undersea volcanoes. Teams of scientists around the world have been studying these organisms to understand their survival ability. which of these is a reasonable source of energy for producers in this habitat?

Whats your take on fish that are endangered/extinct in native habitat?
Posted on Sep 09, 2008 under fish habitat | 9 CommentsI finally found a fish I would be genuinely interested in putting into a five gallon tank - and Boom! - an ethical issue drops in my lap…
The fish is found in ONE pool…..and very threatened in its native habitat….I mean, I like the fish, but I'm not going to encourage habitat destruction…..extinct is one heck of a long time….even sucessful reintroduction of a species can take decades….
I know lots of folks have fish that are threatened (ex. Killifish) - But I'm kind of interested in what your take is on the matter?
Threatened due to aquarium hobby - fishkeeping
I ask because it seems the case with so many aquarium fish….my favorites (white clouds) are extinct in their natural range
It depends on whether the fishkeeping hobby is the reason its extinct or endangered. If its endangered due to habitat destruction, you could be helping to preserve the fish for later re-introduction.
Edit: In that case, do not get the fish unless there is a substantial captive bred population available. Otherwise, even if you manage to get captive bred, you would be taking still be placing the fish in danger because you would be taking fish off the market which might otherwise end up in the hands of hobbiests who have fewer compunctions about destroying the wild population, and would do so if they didn't get the captive bred ones.

My first koi fish: a proper habitat.?
Posted on Sep 08, 2008 under fish habitat | 5 Commentsi was looking into getting a koi fish, but was curious if a large pond was needed right away. i know kois start small (only a few inches) but can grow to be huge (a couple feet long) and eventually need a full pond to live in. i wanted to start off with a tank until the koi outgrows it, but didnt know how fast they grow. how long would i be able to keep a koi in a decent sized tank before i would require a full pond setup?
i was also considering getting a smaller indoor pond at first ad then upgrading as necessary. i live in an apartment currently and dont have tons of outdoor space.
Rule of thumb, 4" fish needs 10 gallons of water and then, ONLY if your filtration is performing at top capacity. (A full functioning colony of nitrobacters)
Koi grow rapidly and secrete waste/ammonia thru the gills, the more they're fed, the more ammonia they shed. It can quickly overwhelm filtration (crashing), turning water toxic with nitrites, resulting in dead fish.
Old saying among koi people " Build your last pond first", in other words plan carefully.
