The twenty gallon is beginning to run,but before I plop my fish in I want to make sure this will be ok.
I've got the majority of stuff from old tanks,gravel and charcoal, given to me by my uncle who has tanks running well and have healthy fish.
Though just about everything is done, I want to know if it is ok for me to put in my fish without cycling now.He is encouraging me to,but I was planning on a fishless cycle,and don't know if it is safe for me to put little Leon in. Any help would be AWESOME,thank you.
