I am a new member from Holland and I just started recently keeping darters in my fishtanks.
Is it O.K. to feed darters Tubifex worms ?

So, I would impale a cube of tubifex worms on the end of a long sharp stick and place it in water at the beginning of the feeding time so that it would hydrate. After a few minutes when the feeding frenzy at the top and middle of the tank lessened I would put the cube of tubifex worms at the end of the stick on the bottom of the tank near their territory. They were immediately drawn to the activity and as the tubifex worms were now hydrated and stringing off small worms they attacked the cube and ate their fill. After about the third feeding they knew this was the feeding plan for them and they would start attacking the cube and stick as it was being lowered into the tank.
I have done this for at least 7 months and they are all active, healthy with good full muscle development and explore other areas of the tank after eating their fill. I am sure that Erica's suggestion would work equally well. The key is that darters can not successfully compete with the fish that eat at the top and middle of the tank. If they are made to do so they will never get a sustaining supply of nutrition and eventually muscle mass will wither and they will waste away.
I hope this is helpful.

Tubifex are a good food, but being extremely pollution-tolerant they can carry heavier loads of toxic metals and organics than most other fish-food animals. If you can find a source that raises Tubifex specifically for fish food, then great, but most of the freeze-dried ones are harvested from agricultural wastewater ponds where they could potentially accumulate high levels of toxins. I use blackworms grown specifically as fish-food in fish-free culture ponds.
