I know there's probably a million threads like this but I'm brand new to the site and joined to get help for my Cory's. I'm a total fish moron (apparently) and I need y'all's help. Had fish as a kid and Bettas as an adult but they seem to tolerate anything. My new Cory's are baffling me tho. I originally got some Cory's for my betta tank, bit decided they were cool and needed their own bigger tank. They weren't healthy for 3 weeks in the betta tank. Well I setup a brand new clean water, new filtertank for them and add 6 neon tetras. All is happy when added to new tank swimming about, within 5 hours all 6 neons dead nose down in tank. 6 hours later my big favourite Julli Cory upsideways, 3 more hrs dead upside down. Soon after peppered Cory acting exactly same, now 8 hrs since then he's dead too. Nerite snails been good the whole time. Brand new baby julli zipping, and 4 red Patty's good, but worry it could all change fast. I feel like the water was soon clean vs the dirty pet store water it killed them...any advice on what's going on? Thanks
