Hi. I just started to stock my 5 gallon (yes, I know it's small) with corydoras hasbrosus. This is a newer tank, and my PH is high, like 8.2! I was told by my LFS that they would adapt. I dripped acclimated them over 6 hours. I added them to the tank, and the largest one died maybe 10-12 hours later. I am assuming it couldn't adjust? It was resting on a plant near the surface... wanting to get out of the water??? The other two seem fine, but I don't know what the warning signs are.
Should I try to lower my PH with peat?
Should I switch them for pygmaeus? Are they hardier?
I was initially going to go with pygmaeus after research, but the hasbrosus are so cute and the LFS guy said either would be fine.
He also suggested one species. But will they school together? There were only 3 of each at the store.
Also, the temp is on the low end but I assume still ok for them at 70.
Any thought welcome! Thanks!!!
