BLACKWORMS Setting up a dedicated tank to try and breed blackworms. Hopefully this will be a good learning experience and hopefully it works. I’ve heard a lot about culture crashes and the smell that goes along with it. Definitely will try to avoid that. I purchased 4oz of blackworms from my LFS yesterday and had to keep them in refrigerator overnight. When I got them home I did a water change with spring water with minerals added back in. Then placed in refrigerator for the night. Today I set up a 3 1/2G tank little less than 1/2 full with same spring water. It has the filter built in to side of tank, slotted openings allow water to go through an ACO coarse sponge in the collection area. Water is then pumped to top of tank and flows through a spout back into tank. Will be adding a air stone to help with surface agitation and fragmentation. I will not be heating this tank, my other no heater tank runs at 68F and this should run close to the same. (Will monitor) Placed a very thin layer of gravel. Then added a vallisneria and some PSO to help with nitrates, both placed with weights. I am hoping some worms will be sucked through the filter system to hopefully be divided during their trip. Also hoping not to many go through at a time to cause clogging. Or get built up over time, will need to keep a close eye on that. I did a small feeding in each tank I plan on feeding these too and as you can guess they absolutely loved them. This will be my first experience cultivating live food. Will also in the near future be trying vinegar eels, daphnia, and mosquito larvae. I will also try my hand at infusoria if needed, hopefully enough is naturally occurring (is that right? Maybe breeding? Cultivating?) in my 125G. Will start feeding tonight, light dusting of krill flake. Will try to alternate foods krill flake, spirulina pellets, vegetable, and fruit. Feedings will be every 2-3 days. As I keep a close eye on water parameters I will change 75%-ish water weekly. Would appreciate any advice or tips or point out anything I missed.
Hey all: I've dabbled unsuccessfully with daphnia in the past, and I'm looking forward to trying again pretty soon. But I'm getting into a little "analysis paralysis" while trying to pick a strain. What is your experience with regard to ideal sizes for breeding? My biggest fish are full-sized congo tetras and my smallest are juvenile multies, rummy-nose tetras, and pea puffers. What's your thinking on the most optimal all-around daphnia strain for these circumstances? If hardiness is a factor, that would make a difference for me too. 🙂 Thanks!
