Please help me with my corydoras

Ok so I just want to know do Corydoras stay on bottom in one spot alot? I got 3 corydoras in 20 gallon..( getting more later). They eat.. some times move are acting happy but then back to bottom.. my mom has corydoras but hers is always moving around so I'm not sure what wrong.. btw water levels are good.. please any info on corydoras will be helpful.

 

Cories like multiples of their own kind. 6 or more preferably. They will be okay with different kinds but most happy and playful with their own. Can you take one or 2 back (if they are all different)? I would go with all one kind for them to be happiest.

What size is your tank?

 

In the pic there are two C.aeneus !

How long are they in ?

I got a 20 gallon.. I been planning on getting more of them but money ran low gotta wait til payday.. and at the time I got the 3rd one they only had 1 left.. I'm gonna try get one more of each breed.. cause I like the different colors

 

I'd return the peppered then and get 4 C.aeneus (2 albino / 2 normal)

 

Albinos are found in C. paleatus, C. aeneus and C. sterbai. These here are C. aeneus albinos. Albinos are not separate species, just a different colour.
