The idea is that the fish can travel from one tank to the next (am i correct)
how does it work ?
The yellow circle is to highlight a hole in the pipe for fish to enter. There is another one on the other end of the "U." I didn't highlight that one as it can't really be seen at all.
You are correct about the purpose. I was surprised how willing the fish (dwarf cichlids and celestial pearl danios) were to move both directions through the bridge. I was concerned that the pump moving water between the two tanks would cause a current in the bridge that would discourage movement but it didn't seem to matter. I was more concerned about water in the bridge stagnating...
20 minute project + time for PVC glue to dry/cure... not bad!
but will still be made out of spare materials
