My new 20 gallon planted tank is just about cycled. Think I’ve decided on a dwarf Guarami, panda cories, and either neon tetras or rasporas. What order should I add the fish? Probably had a species every week or so depending how the tank holds the bio load.
If you're fishless cycling to a decent strength (say 3-4 ppm) you can stock all at once. It's my favorite benefit of the process.
There's actually good reason not to stagger stocking as bacteria colonies will shrink if there isn't a sufficient bioload to support them.
