Tank check today. We recently lost our two breeding guppy males which we hoped to breed for new bloodlines in our breeding section. My females were thinned out this week by a fungul infection that is still running strong even with repeated extensive treatment. We are looking towards buying new breeding lines of Moscow Greens, Cobras, Sunsets, and Fancies for our program when this infection has run its course. A few of our hobby fish are sick and aren't looking good, but I'm not too upset to see my neon tetras go, nasty little fish. They attack anything that moves that is even slightly smaller than them, but I was lured into purchasing four or five last year after our few runny nosed tetras passed away from old age, probably some of my favorite of all our hobby fish. They were very sweet, non aggressive, pretty, and would eat from my hand. I have tried to find them again and again, but to no avail. My dojo loach, by far one of my favorite fish along with my albino bristle nosed Pleco and some seven to eight year old skirt tetras, passed on a while ago, and I would like to replace him soon. I am soon to add either sunfish, bitterlings, killifish, more mosquito fish, or some plain guppies into my heated goldfish and koi hobby pond. The turtles eat fish ravenously in the pond, but they are relatively good snacking on rosy reds and mosquito fish and keeping away from my Goldies, koi, mollies, platys, swordtails, etc., which I'm very glad of. My high finned shark died during a major algae outbreak this year and I am looking for a catfish to replace him, or maybe Sunnies. Anyone have any ideas for good fish for a koi and goldfish hobby pond?
