What it does + when to use it
Yarn-mop egg substrate for killifish + danios + barbs. Fits into the standard aquarium / pond gear stack with specific use-cases that determine sizing and placement.
Sizing for your tank or pond
Match spawning mop capacity to your water volume + livestock load. Oversize by 20-40% rather than match exactly - gives you headroom for stocking growth + buffers against equipment degradation over time.
Setup + maintenance
Follow manufacturer instructions exactly. Most failures trace back to skipped steps in initial commissioning. Document your setup in a notebook + photograph plumbing connections so future maintenance + troubleshooting is faster.
Common spawning mop mistakes
Undersizing for the actual load, skipping monthly maintenance, buying based on price alone (cheap can mean unreliable, expensive can mean over-engineered for your scale).
Cost expectations
Spawning Mop runs $5-$15. Replacement parts (impellers, seals, lamps, media) add $30-$200 per year on average.
