How many Harlequin Rasboras can fit in a 29 gallon?

I agree, large WC should never effect fish negatively. If I could, I would do 75% WC weekly in my tanks. I usually do 35-45%.

Ok, the harlequins are here, all survived the ship and don't seem very stressed at all which is good because I'm a little concerned about how young they are. They only ran from me the first time I approached the tank, after that they were cool with me, they figured out real quickly who feeds them.
These guys must be real hardy because I checked the water they were shipped in and it had ammonia in it.

My nitrates have stayed at 5 so far. I'm going to keep a close eye on it as I'm feeding them twice a day for the first week to help them adjust to the move. My plan is to do a 40% water change this weekend, in my 29 gallon I'll round that up to an even 12 gallons.
 
By the way since no one posted up a pic of the fish in question Ta-Da
