Double Fish
Double Fish
Double each dimension of a fish tank which is the form of a rectangular prism, what would be the ability of two measures?
If Doubling the size of each fish tank which is the form of a rectangular prism, what is the tank capacity also double?
The fish tank is in three dimensions, doubling the height, width and depth would result in a volume 8 times larger. Another way view is that you are doubling each dimension, namely, 2 x 2 x 2 = 8. Try it several times to check this out. For example, a box of 6 x 6 x 6 would equal to 216 cubic units. If doubled to 12 x 12 x 12, the volume will be equal to 1728 units, or 8 times larger. Hope that helps.

Pseudochromis bitaeniatus Double-striped Dottyback $19.99 Double-striped Dottybacks have unique and attractive blurred coloration. The middle stripe has a lavender hue that is off-set by the darker purple stripes above and below. They will accept frozen brine shrimp and krill soon after acclimating to the home aquarium. It is recommended that flake food or pellet food be added to the diet once the fish has become established in the aquarium. This will enhance the vitamins and minerals that they are receiving and keep them healthy. Dottybacks are territorial fish, and should only be kept one to a tank. They will get along with all other types of fish as long as their home is not disturbed by other fish. |

Apistogramma cacatuoides Double Red $16.99 The Double Red Cackatoo Cichlid is a dwarf cichlid native to Peru. These fish have rather understated color in the wild, but have been selectively bred over the years to produce brightly colored specimens like “Double Red”. Males of this variant are tan and gold with brown spots and intense red-orange speckling in the dorsal fin and tail.Apistos are generally peaceful except when spawning. It is best to keep a pair, and as long as there is plenty of room, any other docile tankmates are fine. Provide the couple with a cave area and soft, dark substrate for spawning. Plants make great cover, as well. Feed them a varied omnivore diet of brine shrimp, various larvae and worms, and flake, small pellet, and vegetable matter like spirulina.

Siganus virgatus Double-barred Spinefoot – Large $49.99 The Double-barred or Virgate Rabbitfish ( Siganus virgatus ) has a silvery yellow body with two black bars on its head. The body is also splattered with irregular blue markings forming a complex spotted pattern. Rabbitfish have venomous dorsal and anal spines for protection. These spines are for defense and protection. Rabbitfish do not use their spines to attack or hunt, and most spines occur when the aquarist bumps against the spines or is not careful while cleaning the tank or catching the fish. These fish are generally peaceful toward other fish but may be aggressive toward other Rabbitfish. They are timid by nature and will frighten easily, often taking on a mottled coloration. They are reef safe with caution as they may nibble on coral polyps if they are not kept well fed. Rabbitfish are primarily herbivorous but may eat some meaty foods if green food is scarce. They need algae and other plant matter to remain healthy and do best on a diet consisting of live and dried algaes and supplements of frozen meaty foods. |

Chaetodon falcula Double Saddle Butterfly – Medium $49.99 Double Saddle Butterflies are characterized by the crisp, black, double-saddle markings that extend downward from their dorsal fin. They have black masks and thin, grey, vertical stripes. The dorsal and hind regions are bright yellow. As with many butterflies, they are naturally schooling and find comfort in numbers. They will browse for and consume marine algaes and meaty foods, and should not be kept with corals. Butterflies do best in a fish only tank because of their tendency to pick at sessile invertebrates and corals. In captivity, they should be fed a combination of frozen and flake food fortified with vitamins and some type of vegetative matter. This species should not be attempted by beginner aquarists.
