I want a small fish tank for my desk with a fat little goldfish.

and zebrafish are used as research models for studies in and . The zebrafish is the most commonly used laboratory vertebrate, offering the advantages of similar genetics to mammals, small size, simple environmental needs, transparent larvae permitting non-invasive imaging, plentiful offspring, rapid growth, and the ability to absorb added to their water.
So why not get those health benefits straight from the source and eat the small fish instead?

Most of these fish are too large or temperamental for aquariums smaller than 30 or 45 gallons but a few especially “pygmy” pygmy angels can be kept in smaller tanks. They should still not be kept in nano-tanks or with exceptionally docile tankmates but can still suitable in small tanks with only one or two other fish. pictures of small fish | Should you keep it?

Being a big fish in a small pond is great for some people: personally, I got a lot of opportunities that I would not have had otherwise. You do feel special, and thats not the worst thing in the world, however, it can make "learning to fail" that much more difficult when you begin to face failure. Though college life is not an accurate representation of the world, it is the next closest thing and surely a large step up from high school. Having the experience of being the small fish in the big pond of college has above all else taught me the importance of pushing myself to do my absolute best, a lesson I continue to learn every day with every failure and every success I face. Okefenokee pygmy sunfish do quite well in planted aquaria. They mix well with a lot of our small tropical fishes, making great tankmates with pencilfish, small tetras, or mini rasboras. Provided their tankmates will not eat them and are not voracious enough to gobble down all the fish food, they'll do just fine. Pygmy sunfish can be somewhat difficult to feed in the aquarium, often demanding small live foods, such as blackworms or Daphnia, but generally transition to at least frozen fish…When it comes to the ocean’s small, silvery, schooling fish we are most familiar with coastal species like sardines, anchovy and herring. However, other lesser known fish—many with fairly funny sounding names—make up the most abundant groups of fish in the ocean. Possibly the most abundant and widespread of all are “myctophids”. These small fish are critical to supporting a healthy ocean food web. While myctophids eat zooplankton, they in turn feed countless ocean animals including salmon, halibut, tuna, dolphins, and whales. During the day these fish hang out in the deep between 1,000 and 4,000 feet below the surface. At night, however, they migrate up to just 30 feet below the ocean surface. Through these daily vertical migrations, myctophids actually act as a massive biological pump, rapidly transporting carbon from the surface to deep-sea ecosystems. So, not only are they important as prey for ocean wildlife, they are a major part of the global carbon cycle.With new federal regulations issued today, the National Oceanic and Atmospheric Administration’s National Marine Fisheries Service (NOAA Fisheries) is prohibiting commercial fisheries for myctophids and other small forage fish in the Pacific Ocean off the U.S. West Coast.Most of the islands in the Central Pacific are very young in comparison with continental landmasses. They began to develop deep in the ocean through and eventually emerged above the water creating completely new habitats for different types of organisms. How numerous species of plants and animals colonized these novel habitats and how they have survived together within the unstable environment of a volcanic island are intriguing questions that have been asked repeatedly through the history of evolutionary biology. The fascinating story of a small freshwater fish can help us to find some possible answers.
