discovering cryptocoryne: care and cultivation

[noviceguy]

Just added some Cryptocoryne to my tank a couple of days back and they're already looking a bit off. Seem to be struggling, to be honest. I know it's still early but I'd rather catch any issues now and sort them out quick.

It's normal for Crypts to melt in a new setup, they'll send out new growth over time though.

Thanks for the info, that's a relief

Yeah, just looked into it, apparently it's a common thing with Crypts - they just melt away initially, but they'll regrow new leaves over time.

Mine did the same, they melted down but then bounced back, stronger than ever.

When you first get Cryptocorynes, inspect the rhizome for any soft, squishy black areas - these are rotten bits that'll spread and kill the plant if not removed. A sharp knife will do the trick.

Most Crypts die back after being added to an aquarium because they're grown hydroponically - roots in a damp medium, leaves in the air. When submerged, the leaves rot and get replaced by aquatic ones.

Transplant shock is another issue - sudden changes in temperature, pH or GH can cause it. And be careful when transporting them - leaving the bag in a hot car can be disastrous. If the bag gets too hot, the plants essentially steam in the plastic bag, leading to a quick demise after being added to the aquarium.

Even a big water change can cause C.wendtii to melt, even after they're established. I've seen it before - large growths melting after a water change, only to come back later. This time around, I've been lucky and avoided a big leaf die-off.

A one-off large change can cause issues if it significantly alters water parameters. However, consistent large water changes are not typically a problem. I've been running three tanks with C. wendtii, each receiving 75% weekly water changes, and I haven't seen any melting occur in these tanks.

That sudden drastic change is the culprit. Most plants aren't fond of it, but Crypts have a unique way of reacting. You can't help but breathe a sigh of relief when you see new growth on your new plants.
