Only a few coastal animals can be kept alive for several months (for example gobies and blennies, palemons and some actinians).The related bibliography is thin and pretty vague. However, one can note that:1° all authors have observed a change in the chemical constitution of the aquarium water, without being able to explain it;2° all attempts at keeping alive fragile animals or plants (mostly algae) in an aquarium running in closed circuit have failed;3° unlike fresh water aquariums, no publication, at least to our knowledge, deals with PH variations and their impact on the physiological state of the... |
