That is one awesome cat! I've wanted one ever since I saw it on river monsters but there's no way I would be able to house such a beast. What are your long term plans for it when it starts outgrowing it's current tank and any future tanks?
Good question. I always joke about having a Monster BBQ when it gets too big. I just shot some pic's to a few local MFKers saying the Goonch is really growing. It's in a 210 and it's touching the front and back at the same time so it's 2' for sure, not including the streamers.
I've been planing to take apart a couple 125's I have saved, using the glass to make a 6X6X2 using the 125's and a plywood/fiberglass bottom. That would be 500+ gallons. The fish doesn't move much, it's not a huge concern at the moment but another foot and it will be too late.
