That's exactly how I felt, luckily my mom has several indoor pond and river set ups, she has them in a grassy riverbed habitat. She feeds them pellets for me and on the weekends I visit and grab a few of her goldfish or koi babies and watch them hunt. I didn't know then that I was gonna catch the saltwater bug when I took on the project of changing a freshwater Walmart gsp to salt... Once I started in with my puffys 40g and live sand and rock I was hooked. Bioload on a 10g puffer tank is insanely high- is he a saltwater with CUC or are you doing pwc all the time? He is gorgeous, as is your cichlid tank, I'm sooo envious, lol.
