SPECIAL PURPOSE AQUARIUMS

This category includes:

• breeding aquariums, often a simple glued glass tank with no soil, for temporary use;
• hospital-aquariums;
• large aquariums. These are large by virtue of their length, as their depth and breadth cannot exceed certain limits for technical and practical reasons. They sometimes present installation problems, due to the weight on the base and the special materials required for their construction.

Large tanks are often given over to large species which require ample living space on account of their size. They can also be used for the other purposes mentioned above, because it is generally considered that the bigger the aquarium, the easier it is to maintain its equilibrium. Contrary to what is often thought, their maintenance does not imply more problems if an equilibrium is really achieved.
