4-5 minimum to be truly happy (stable).How many do you need for them to be stable?
Depends what other fish you have in your tank regardless of whether you have other bottom feeders or noti thought it would be stupid to start a new thread, so i just want to add to the last question.... what is the maximum you can fit in a 24x12x12, 15 gallon tank with no other bottom feeders?

12 works well! i have kept 6 together before and 4 died due to a bacterial infection. the remaining two were very obviously distressed they had lost their friend's and hid all day long until i added the new 10.
only a african butterfly fish and possibly some lemon tetras
