%0 Journal Article %T The red neon, Paracheirodon axelrodi (Schultz, 1956), is able to survive in distilled water %A I. Valentin Petrescu-Mag %A Dan Rasiga %J Extreme Life, Biospeology & Astrobiology %D 2009 %I Bioflux Society %X In the current paper we report on the ecophysiological adaptation of the red neon toextremely low water hardness (nearly zero). Such adaptations of aquatic vertebrate species (either fishor frogs) to extreme environmental conditions show a large plasticity of this group even if, by definition,the aquatic environment is quite stable and homogeneous. %K ecophysiological adaptations %K red neon %K extreme environment %K low hardness %U http://www.elba.bioflux.com.ro/docs/2009.1.49-50.pdf
