For trade, a piece of red cap about 5" across. It got so big it broke free. Willing to break into smaller pieces or sell for $20. LMK through PM's if you'd like to trade. I recently saw a piece in similar size sell for $50 at a local shop, save yourself some cash... If you have a smaller tank, 75g or less, be kind and ask me to split it with someone else... It will grow so fast it won't fit in your tank long.
