Tetra Housing tools: what they help with
These calculators size your tetra's living space: the minimum and recommended dimensions, how much bedding or substrate to buy and what fits in the space you have. Too little space is one of the most common welfare problems in pets. The right size gives a tetra room to move, rest and behave normally.
What to know about housing and enclosure size for tetras
Tetras are schooling fish that become stressed and nippy in small numbers, so keep at least six of one species. They prefer soft, slightly acidic water with planted cover and subdued lighting.

A practical tip
Treat the minimum as the floor, not the goal. Bigger is almost always better, especially for active or social species.
