What equipment should be equipped with a coverless glass fish tank?

Lighting: Buy a light stand, or DIY it yourself. If you don’t raise grass, a light tube with tens of watts is enough. Filter: It depends on what kind of fish you raise. If you find it troublesome, just install a filter cartridge. Or an internal filter; if you want to raise larger fish, it is best to install a filter, which consists of a filter tank + submersible pump + filter material + water pipe. They are sold in general fish stores and there are many online. A pump with a flow rate of 1000L/H is enough. Insulation: If you want to raise tropical fish, a 2 or 300W heating rod will be fine, but without a cover it will consume more electricity
