The tank is 3 foot long by 1 foot & 1 foot high but I'm hoping to get a bigger one soon. There's only the one fish in there - he's about 7 inches long. There's no plants or anything in there anymore because he keeps digging everything up
I change the water pretty often because the tank seems a bit small, & I check the pH & everything. He's acting normal. I thought maybe he could be injured from trying to jump out all the time?
