These worms will have your fish spawning in days. Most cichlids love them. Have even seen Aulonocara hunt them via sonar once worms burrow into substrate. One time a shipment was lost due to airlines failure. This firm covered the loss despite no insurance. That is first class service.
Unfortunately they will not take credit card information via phone and they do not have a secure method of submitting credit card number via internet.
Again the worms will get the fish spawning.
