  2. Quite subjective..... different books and web recommend diff suggestion... some say stocking is about 1" of fish per 3 gallons for fish only and some say * For small to medium fish, the rule is 2" of fish for every 10 gallons. * For medium to large bodied fish, the rule is 1" of fish for every 10 gallons. But I ever see ppl kept 30fishes in 20-25Gallon tank without casualty... and long thriving too.. But on the other hand we can apply above as ROT, also provide a good home to our livestock.. I strongly believe tank maturity first priority (How old is your tank?)... 2nd:- Fish nature behavior & habitat compatibility (Your case looks ok, except for Dragonet, makesure have enough pods/live foods for him to consume, and some reefers having hard time with RG Vs Firefish but in general they r ok) also your filtration system and water volume play a parts... If all above fulfill, I believe should not any issue as your fish selection not those big size & aggressive species and greedy fish like tangs family....... Cheers and Happy Reefing..

  17. Blue Crab Mating from bluecrab.info Mating The blue crab's activity begins in early spring, when the waters of the Chesapeake Bay warm and the crabs stir from their dormant state. All winter, the females have remained on the bottom of the Bay, most of them in the deepest water. The mature males have been buried in the sediments of the estuaries, and the juveniles have sheltered in shallow-water habitats. During this time, the crabs have not eaten or ventured far from their resting place. With the arrival of spring and warmer temperatures, the male and female crabs begin to move away from their wintering grounds to look for food or seek out a mate. Mating occurs primarily in relatively low-salinity waters in the upper areas of estuaries and lower portions of rivers. Mating takes place in areas where female crabs normally go to molt—shallow areas with marsh lined banks or beds of submergent vegetation. Blue crabs mate in the Chesapeake Bay from May through October. The primary mating seasons for blue crabs in Louisiana are April through June and September through October. Extended periods of low temperatures will usually significantly shorten the mating season. The male may mate during its third or fourth intermolt phase after it matures. Females mate only once in their lives immediately following the pubertal, or so-called terminal molt. Precopulation When a mature male encounters a female that is about to molt to sexual maturity, the male will perform a rather elaborate courtship ritual, or dance, to get the female's attention. Upon initial contact, the male will stand up high on the tips of his walking legs. He will then wave his claws, stretching them out wide, extending them fully outwards, and will begin to fan pheromones (a chemical scent which attracts females) contained in his urine towards the female with his swimming paddles. Finally, he will snap his body backwards and kick up sand with both his swimming and walking legs. Should the female fail to respond, he will repeat the process again. The female shows her interest by rocking and waving her claws in and out. She may or may not approach the male, turn around backwards, and attempt to wedge herself under him. Still waving her claws, the male responds by tapping and rubbing her claws with his. Soon she quiets down, tucking her claws into a submissive posture, and allows the male to clasp and carry her with his walking legs. In this position, the mated pair is called a "doubler" or a "buck and rider." She is right side up and facing forward. This is also known as a precopulatory embrace. The male will "cradle carry" the female for 2 to 7 days until ecdysis (molting) is imminent. This serves two purposes. First, the male is able to protect the female from predators. Second, it assures that the male will be present during the brief time that the female's shell is soft and she's able to mate. Once the female begins to molt, the male releases her and stands guard over her by making a cage with his walking legs. The molting process may take several hours to complete. This terminal molt marks the female's transition into sexual maturity, and is usually the last time she will shed. During this transition, her abdomen changes from a "V" shape to a more rounded "U" shape. She is now called a "sook" and will only mate this one time in her life while her shell is still soft. The female must rest briefly to fill the voids of her new shell with water. Next, the male turns the her upside down so that their abdomens are touching, clasping her with his walking legs. This is known as a copulatory embrace. Copulation The female extends her hinged abdomen, exposing two genital pores known as gonopores. The female gonopores are large triangular openings in the sterna of the sixth thoracic segment, in line with the third pair of legs (see female anatomy for more information). The male inserts his gonopods (see next paragraph) into the genital pores and transfers seminal fluid which contains microscopic packets of sperm, called spermatophores, to the female. Each spermatophore packet contains several thousand sperm cells. Copulation will last from 5 to 12 hours. Postcopulation Following copulation, the female is once again clasped and cradle carried, right side up, facing forward, until her shell has had a chance to fully harden, about 48 hours. This is known as the postcopulatory embrace. Once released, the female instinctively begins a migration to higher salinity waters so that she may spawn. Mass migration of schools of "sook" can be observed and plotted down the bays in June and again in August. The male stays put and will mate with several additional females. During the female's migration, the egg cells in the her ovaries will begin to develop and will be ready for fertilization within one to two months after mating. Most females spawn for the first time two to nine months after mating, usually from May through August the following season (they overwinter before spawning by burrowing in the mud.)
  18. Bro Terry, as far as I know they r not photosynthetic... they need routine feeding and trace element.... not easy coral too... Cheers and Happy Reefing....

  22. Jelly Fish All Around The jelly fish came to this lake in Palau through a tunnel which connected the sea and the lake long time ago. Now the tunnel have closed, and the jelly fish came to have no poison in an environment where there's no predator. They live by photosynthesis because they cannot feed on anything in this lake. This lake is such a heaven to them that there are just so many of them living here.
