Are saltwater fish easier to take care of? Ease of Maintaining Similar to the fact that freshwater aquariums — but not all — are cheaper than saltwater, freshwater takes are also generally easier to maintain and care for. There are so many variables within a saltwater environment that can make up-keep and care a little more difficult and time-consuming.

How high should the water level be in a fish tank? What Is the Optimal Water Level? Though each tank is slightly different, a good rule of thumb is to fill up your aquarium to about an inch below the top of the trim.
What kind of vision do fish have? Fish retinas generally have both rod cells and cone cells (for scotopic and photopic vision), and most species have colour vision. Some fish can see ultraviolet and some are sensitive to polarised light.
How do fish actually mate? Most fish spawn by releasing eggs and sperm directly into the water column to achieve fertilization. This can be done on a one-on-one basis or in a group. Many salmonid species take the more intimate and monogamous approach. One of the benefits of this strategy is that only one male’s sperm fertilizes a batch of eggs.
Why can fish breathe in water but not on land? In water, the projections on the gills float, so each is surrounded with water from which it can absorb oxygen. On land, these all collapse together, blocking most of the surface area. So they don’t work well and the fish suffocates. Lungs increase surface area by having many tiny pockets, which don’t collapse in air.

How far out is inshore? Inshore fishing is typically defined as anything within 9 miles of the shoreline and in water 30 meters deep or less. Therefore, inshore vs. offshore fishing is a distinction based on both how far you are away from shore and the depth.
