Fish growth and Flow

[GMaquarium]

Some time ago I noticed a correlation between fish growth and water movement in the aquarium. Lately I am seeing it more with some of my tanks and fish as time goes on.

What I began noticing is fish in tanks with lower/slower water movement grow faster. Fish in high flow tanks grow slower. Although this isnt the case for all (gary m. has fat fish and high flow). I am basing this on many tanks. Tanks that have been around for at least a year and fed same foods. I think fish in higher flow tanks must burn more energy to keep up.

Water flow definitely affects a lot of things in an aquarium. IME fish in a slow flow aquarium can (possibly) get chubby!
Related note: "Junior" (my Emperor Angelfish) can swim directly in front of my Vortech MP60 at full blast. So there's a correlation between the size of the species and amount of water flow and rate of growth.
Apparently the MP60 at full blast isn't high flow for a large Emperor Angelfish :spin2:

Makes sense, just like riding the exercise bike! Burning those calories!

Gary does that Emperor Angel behave in your reef tank? Does he nip at anything?

but (long story short) the Angelfish will nip at whatever it wants
