It is postulated that the fanning behavior of the fish and removal of parasites promotes the health of sea anemones which contain A. ocellaris fish. In addition, the anemone provides protection for the fish with its tentacles, however, the fish's mucus protection prevents it from being stung by the tentacles.
Amphibians are ectothermic, anamniotic, four-limbed vertebrate animals that constitute the class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all tetrapods excluding the amniotes (tetrapods with an amniotic membrane , such as modern reptiles , birds and mammals ).
The fish's hyomandibula bone in the hyoid region behind the gills diminished in size and became the stapes of the amphibian ear, an adaptation necessary for hearing on dry land. [23] An affinity between the amphibians and the teleost fish is the multi-folded structure of the teeth and the paired supra-occipital bones at the back of the head ...
For starters, investing in the best fish food isn’t just a ‘nice to have’, it’s a necessary part of fish care. The best top-quality fish food ensures your school gets the right diet to ...
Care of offspring by males may evolve when natural selection favouring parental care is stronger than sexual selection against paternal care. [8] In approximately 1% of bird species, males exclusively provide care after eggs are laid. [9] Male-only care is prevalent in a variety of organisms, including fish and amphibians.
There are a wide range of frogs, salamanders and caecilians that can be kept in an aquarium. Some of these are not found in the pet trade. This is usually because they're either too big for most commercial aquariums (ex: giant salamanders), are endangered (ex: achoques), or both.
Lists of aquarium life include lists of fish, amphibians, invertebrates and plants in freshwater, brackish and marine aquariums. In fishkeeping, suitable species of aquarium fish, plants and other organisms vary with the size, water chemistry and temperature of the aquarium.

Amphibious fish are fish that are able to leave water for extended periods of time. About 11 distantly related genera of fish are considered amphibious. This suggests that many fish genera independently evolved amphibious traits, a process known as convergent evolution .
