it does look similar but In any case about how long do crypts take to start to send off runners and spread because it's been in the tank for almost a week and it hasn't melted or showed any signs of deterioration so I'm thinking it's in pretty good health and I was hoping it would spread out a little towards the front of my tank soon (I will be adding temple Hygrophila behind it) and so that's why I've been trying to figure out the species so I could research it a little more and try to get a guess on the growth rate, but how long does that usually take in your experience? Also I may reposition it after I add the Hygrophila so I haven't added a root tab just yet but I will be once I get all the plants settled in their final spots.
