Ive had a couple of trumpet nosed knives for awhile now, and theyve been doing well on frozen blood and tubiflex worms with a little brine shrimp thrown in for variety. But I just recently picked up a Campylomormyrus tamandua, an elephant nosed mormyrid that also roots around in the substrate for worms and other benthic invertebrates. So now that Ive three trunk-mouthed worm eaters I think its about time to keep a colony of live worms for them. Ive looked into it a little bit, but most of the sites dont go into much depth about whats involved with keeping a colony and how much work it is. I need everyones opinion about the different types of worms available (black, red, white, grindal, etc.) and any experience on what it takes to keep a culture of fish spaghetti going. Thanks!
