i think the fish will swim through no prob.. thats what fish do swim and explore good luck bud post some pics when done.... ps instead of using pvc try clear acrylic tubing... lot more money but def look so cool
I've always wanted 2 tanks connected...would be so cool to have 2 custom acrylic tanks predrilled so you could have an acrylic tube connecting them so your fish could swim between either tank if they wanted.
The entire purpose of connecting the tanks is give to different habitats for the fish. One tank is gonna be mostly artificial st00f with a load of hiding places (30 gal) and the other one is a all natural (live plants and sand) setting with larger open spaces... also one side will be warmer than the other so it should be interesting.
