This is a privileged moment between the aquariologist-technicians and their proteges. Feeding allows them to take stock of the general condition of the animals, after carefully observing their behaviour. To meet the feeding requirements of the different species, food is varied, as far as volume, quantity and of course quality.
Some animals are easy to feed. Distribution of food is a simple formality. For others, patience and cleverness must be used: shrimpfish or frogfish will only eat living prey. Others, like the leopard moray eel and the stonefish, must be fed with forceps or hand-fed individually.
Aquarium filtration
Water is filtered, then sterilized, before being distributed to the tanks. Some operate in open circuit with a permanent water renewal, other in semi-closed circuits or, in the case of the tropical tanks, in totally closed circuits.
All these devices enable the circulation of up to 400,000 litres of water per day. All the key areas of the system (pumps, filters, pipes...) are double-checked to prevent any possible failure.
Locals hypothesize that the legacy of Italian blood and culture in Cologne, colonized by the Romans more than 1500 years ago, makes the people more jovial and lighthearted. Cologne is the largest city on the Rhine.
Kolsch is not only the dialect spoken here but, also the name of their own top-fermented beer. There are more than 4,000 pubs, restaurant's and brewery taverns in Cologne.
Unlike many of the world's large cities, Cologne, with a population of over a million, gets better every day, there are more things to do and see, more new and innovative buildings... more
Travel is an opportunity to learn, whether geography, languages, history or other subjects.
Cologne is situated on the beautiful Rhine River.
