>>> I used to keep fish in the water tanks. Then I got to thinking... is it >>> better for horses to consumer algae or fish pee and poop? I don't know >>> the answer to that, so I haven't had fish for a few years.
That choice is probably an even (or approximately) trade-off, although if it's truly in equilibrium, the algae should use the fish poop, and the fish should eat the algae. However, if the fish really help keep down mosquitoes, then there's a vote for fish. I see a few mosquitoes around our goldfish pond, however, so I'm not sure how much they really help mosquitoes. Also, be careful that your horses don't "gargle" in the water tubs after you worm them. Per my farrier, apparently wormers don't do much for the longevity of goldfish... :( Karen Thomas, NC
