I have recently introduced to relatively immature German Rams (Microgeophagus Ramerizi) to a commmunity tank containing to two larger Bolivian Rams (Microgeophagus Altispinosa). Question: Will I get Rams with a taste for Bratwurst, Beer and Hot Latin Salsa and Chilies or will they breed exclusively with their own species (or genus, whatever!?!)? Obviously I don't want them to interbreed, so what can I do? The aformentioned Bolivian Rams (Microgeophagus Altispinosa) seem to have a case of worm/nematodes. Symptoms: tiny red pin shaped "spikes" hanging out their anus and have clamped fins. I've tried Hexamite unsuccessfully and a deworming medication with pellets and frozen brine shrimps. I actually removed several with a tiny pair of tweezers. All remedies aside, they still have these damn worms sticking out their butts!!!! WHAT CAN I DO?
