Founding Fish

Oceanic adult herrings spend their days deep and come up to the shallows at night to feed, so you are not very likely to see them. Small ones may be more commonly found in inshore waters. Sometimes the marinas and inlets are full of tiny immature herrings known as "Peanuts." Saltwater herrings ascend rivers to spawn. All herrings are primarily filter-feeders, although larger ones may also be predatory on small fishes, squids, and other prey.

Shad is the largest member of the herring family. They are highly sought-after as sport fish when they make their annual upriver spawning migration in the spring. Some landlocked shads may spend their entire lives in freshwater. Menhaden is another of the many local species of herring.

All herrings and their small cousins sardines share the same saw-tooth scales on the belly, giving them the name "saw-bellies". That's why the Knights of Ni demanded that King Arthur "cut down the tallest tree in the forest with ... a herring!" -- from Monty Python and the Holy Grail

Lighting Basics

Feather Blenny

An unplanted aquarium should receive 6-10 hours of light per day. This can be either artificial or natural light. Direct sunlight should be avoided. While in the short run darkness does the fish no harm, how would you like to be kept in the dark most of the time? On the other hand, excessive lighting can lead to dangerous brown or green algae blooms, which can upset the entire balance of a tank, and eventually kill everything. This is caused mainly by excessive amounts of direct sunlight and is not really a problem with artificial lighting.
