HI so my gourami is swimming all funky and laying at the bottom of my tank sideways. I have an Aquaponic tank (very small) trying to be set up and I was gone for the weekend and had a friend taking care of my pets, well to two tetras died (one found the other MISSING?!?!) and the gourami is swimming weird. Can I fix this or is my gourami heading for the big blue ocean in the sky??
