I have a 20 gallon high tank with 6 zebra danios...1 honey gourami and 3 emerald green corys (Had 6, but over time 3 died. 1 was a cpl weeks ago). Went to Petco and they didn't have any corys except 2 albinos... must be a cory shortage... Anywho.. I wondered if I should get 3 more emerald green corys if I do find them or just wait until they eventually die and then hopefully find smaller corys?? I had smaller ones before...the standard cory I guess you'd call em.. they were smaller. I didn't realize the emerald green ones get up to like 3 inches or whatever. Never had any problems with them and they have been great in the tank. Didn't want to mix them with another school of corys and possibly overstock the tank. I'll hafta wait anyway since I can't find any nearby.. Even Petsmart doesn't have any. Just wanting to know what I should do? I thought about getting some from The Wet Spot where I got my honey gourami, if they have any, but like I said, don't wanna overstock the tank or anything. thanks in advance for the help.
