Eeek.. thats why i set up the tank before i got the frogs.. not only that because you alreayd have the frogs its not a great idea to add real plants until you can have them established and make sure there are no pesticides on them. Otherwise I would say I paid at most $3 for one of my plants. the other two were about $2.. they are small but growing well now. Good luck, i hope you can get some coverage in there for them soon.
