I won this 10g Tank KIt from Aqueon at my clubs December meeting in a raffle. Wisconsin Reef Society and had my sons 14 and 11 help me set it upo for them, pick out the gravel and fish, etc. I found a plastic turtle somewhere, and put it in a cup of water- it sank! So I added it to my FW DT. Showed it to my sons, and the 11y/o decided to add a bit more flair. We tried them in a cup of water- they sank too! So, here's my current FW DT- we added a catfish too to help keep the bottom clean.
