Who this list is for

Corydoras do best with a setup that accounts for a social group and a bottom-oriented layout. This checklist is for an indoor freshwater aquarium sized and conditioned for the specific Corydoras species you plan to keep.

How to use this list

Begin with a 20-gallon long aquarium or larger, a level stand, and a secure lid. Add fine smooth aquarium sand, then install the sponge filter with air pump, airline tubing, and check valve. Set the aquarium heater and digital thermometer, condition water, and use the freshwater liquid test kit. Arrange smooth driftwood, broad-leaf plants, low aquarium caves, and floating plants before setting the low-flow aquarium light. Keep the feeding dish, sinking bottom-feeder pellets, gentle-flow gravel siphon, and aquarium-only bucket nearby.

Do not use sharp or rough substrate in place of the fine smooth sand listed here. Avoid strong flow when the checklist calls for sponge filtration and a low-flow light setup. Do not assume every Corydoras species needs the same tank size or water conditions; check the specific species before stocking.

What is on this list

The list covers tank support, lid, sand, filtration, aeration, heating, water testing, simple decor, plants, lighting, and bottom-feeding supplies. It also includes a gravel siphon with gentle flow control and an aquarium-only bucket. Cross off equipment you already own.

Before you go

Measure for the 20-gallon long footprint and confirm the stand is level. Match the heater, sponge filter, airline tubing, and check valve to the tank. Research your chosen Corydoras species before making water-condition decisions or adding compatible companions.
