 Posted: Mon Jul 19, 2010 11:24 am Post subject: Cory breeding and Alder cones |
  |
|
| Hi all, I'm going to try breeding my first corys soon, C trilieatus (sp?). I chose them because they like the same temps as my S barbatus. Anyways, I have heard so much about Alder cones being used to prevent fungused eggs, but can't find anyplace that says when they should be collected, i.e. when closed, open, etc. Is anyone able to help me? |

Being curious too, I picked some a week or two ago on a trip to the Birchwood area in Wisconsin. Some cones were open, dry, and still hanging on the tree left from last year's growth, some were still young, closed, and very green from this year's growth.
The first ones I tried in a small container of tank water were the dried ones. After three days in a small container with an air stone bubbling, there wasn't any color change to the water. I was expecting at least some color change to the water. Maybe weak tea colored? Nothing.
The second ones I tried were the green (immature?) cones. After two days in the container with an air stone everything was covered in mold or fungus, probably from the rotting cone. The water was a yellowish color. If the goal is to avoid fungus, this did the opposite.
Still not sure of the answer, but these have been my experiences so far. I might go back this fall and pick a few more. We'll see if later in the season is the answer.

| HI you can find alder cones around wet areas in the woods on alder trees you pick them when they are dried they really dont give off tanins in the water but do stop the eggs from fungus but if you leave them in the tank long enuff they will lower the PH I sudjest using dried oak leaves and alder cones they work great for breeding cores |

This is cool. I had not heard of this use of alder cones.
Are people using these for all sorts of eggs (e.g. angelfish eggs too) or mostly just certain sorts of fish (e.g. the catfish you were talking about)? |

| Late reply but thanks a bunch for the alder info. I thought I'd have a ton of oak leaves this fall, but it seems our sole oak is inundated with some sort of parasite so I doubt those are a good one to use. Oh well. |

Sorry, I've had serious connection issues, which is what I get for living in the boondocks 
Jordyndean, any luck with what exactly? I've found a bunch of alder trees by my place and hopefully will get more than the 5 cones I already picked. My C trils havent spawned yet, but the weather's been horrid for getting cold water fish to cooperate. Maybe when fall comes. |
