ok, typed in corydoras elegans in google and this is one of the sites that came up: http
/aquaworld.netfirms.com/Siluroidei/Corydoras/Corydoras_elegans.htm
it says they like temps 20-24degreesC, pH 6.0-7.5 and hardness 2-20 somethings (doesn't say)
another site: http
/www.aqua-fish.net/show.php?h=elegantcory
temp:22-26
pH: 6-7.6
hardness (dgh): 4-18
yet another: http
/www.peteducation.com/article.cfm?c=16+1911+1919&aid=2448
temp: 72-79F (yes, thats farenheit, not celsius thank goodness)
pH: 5.8-7
hardness (dh): 2-12
ok, thats just straight off the web (
), so hopefully someone who has kept them before will come along offer their opinion
also, maybe find the average as a guide from the 3 sites
