The spanning tree protocol and algorithm were developed by a committe of the IEEE. Currently, the IEEE is attempting to institute enhancements to the spanning tree algorithm that will reduce network recovery time. The goal is to go from 30 to 60 seconds after a failure or change in link status to less than 10 seconds.
Axolotls eat worms, insects, small fish, and just about anything else that can fit inside their mouth and swallow whole, including other salamanders. In the lab, axolotls are fed brine shrimp, California blackworms (Lumbriculus varigatus), and salmon pellets. Terrestrial salamanders are fed crickets, worms, and beef liver. In the Ambystoma Colony, aquatic salamanders are fed food pellets.
Axolotls range from $20 for juveniles up to $35 for adults. A standard starter set up will cost about $85, including filter pump, gravel and tank pH test kit (larger rocks, plants and other ornaments may cost extra). More efficient and preferred filtration systems can cost up to $165. large axolotl can grow to about 30 cm and can weigh up to 300 grams. They have poor eyesight with no eye lids and are quite sensitive to light, so remember to house them away from direct sunlight or bright aquarium lights. Interestingly, axolotls are able to regenerate lost body parts over time.
