My gf wanted to go into Petco the other day to look for stuff for her dog. I decided to check out the fish department and make myself angry. Actually, there was no one dead or sick fish and the whole area was neat. I saw they had some plants in these weird looking tubes. I read the packaging and it they were live plants! The roots were in little wet pepple looking things. Has anyone purchased these before? They actually all looked very healthy and were $3.99 each.
