I bought the magic fish for my daughters for Christmas. We followed all the instructions as indicated but we could not grow the shrimp. I went back to the store where I bought it and they gave me some silly story about boiling the water first which is not on the instructions. i them e-mailed home mark and a lady by the name Marina Billings read the e-mail. i sent two more e-mails but i am still waiting on a response from here. can you imagine the disappointment on my girls faces? The service is absolutely appalling.
