I have two tin foil barbs. Both are about 13" to 14" long. They are in a 75gl right now, but will be moving to a pong in Savannah, GA this sping. Hate to see it since I have had them for about6 years.
8 inch common plec, in a 55 gallon. Tank upgrade planned for this year. (to at least 125 gallons) I think we should include tank sizes also, if you are brave enough to post it. Let's not turn it into a flame thread though.
