Woke up this morning. found my pleuro with a huge hole by its belly. I say Lung fish. But this Snakehead was acting very weird for the past couple weeks. It would twitch for no-reason, It wouldn't eat.It would bolt around the tank for no reason also . It did not eat for 3 days . All of this was happening before I introduced the Lungfish. So I wonder what got him last night. oh well Fish Happens. At least North American Pet has some for $12.99 i beleive. So off I go.
