that's probably planaria. nothing to worry about. You may have overfed the crayfish or there's uneaten food left around somewhere in the tank.


i got a small 20cm tank, inside only put 1 crayfish. 1 green tea bottle DIY filter, 1 power head.
I normally feed raw meat and feeder fish to the crayfish, feed every 2 or 3 days. when I cleaning the tank today, found out lots of small worm about 2~6mm inside the water, the worm just like bigger micro worm. what it can be and why it's inside my tank.
not sure if pic will help as it's very small hard to take the photo.

nothing to worry about that. It's just a case of overfeeding. These guys appear when you do so. Reduce feeding or WC to make them go away. Alternatively, guppies or mollies eat them![]()
