As summer winds down, all my outdoor fish have been moved back inside except for the goldfish in the inground pond. I began the process of collecting them a couple days ago, simply because catching the fish out of that pond always seems to take forever. This year is no exception.
My big home-made minnow trap has produced exactly zero of the desired results; not once have any of the original goldies, now all in the 5-6 inch size range, shown any interest in entering. I have been going out after dark with a headlamp and a couple of long-handled dip nets and have managed to snag 5 of the 22 large ones; they are a bit dazzled by the bright beam of the headlamp and usually can be netted without much fuss. I am quite amazed at the difference in colour between the sickly waifs in the "feeder" tank at the LFS...and the magnificent orange beasts in that pond. Natural sunlight? Diet? Don't know, but...wow!
Inside, the first of them look terrific. After acclimating them to the indoor water temperature, which is only a few degrees off from the outside pond temp, they are gliding placidly about in the tank and they already provide the peaceful look and "vibe" for which I was hoping. I am becoming a goldfish convert...
...except for one thing...
The outdoor pond has water that is tannin-stained but clear. There are luxurious growths of hornwort, guppy grass and many native emergent plants, along with driftwood and rocks. Seen from above, the big, brilliantly-coloured goldies are impressive and eye-catching. But...less visible are the hundreds of baby goldfish that have somehow appeared in the pond! A net run through the hornwort thickets will always produce a half-dozen or so, ranging from about a half-inch to 1.5 inches in length. I am embarrassed to admit that I did not realize young goldfish don't seem to develop their orange colouration until they are at least an inch or more in length, which makes them pretty inconspicuous especially when viewed from above.
So...my C.dimerus cichlids have eaten spawn after spawn after spawn of their young. My Xenotoca livebearers were wiped out by polluted water after a couple of birds drowned and decomposed in their stock tank. Even my wonderful little Heterndria colony grows pretty slowly, largely as a result of predation by aquatic insects called Backswimmers.
But only a few weeks after grudgingly admitting that I kind of liked goldfish and finally wanted to devote some time and tank space to them...I find myself in possession of hundreds of them!
As I stood next to the pond, with a bucket of a hundred or so youngsters at my feet, I wondered out loud where they all were coming from. My wife, helpful as always, began "Well, when a boy goldfish and a girl goldfish love each other very much..."
