Do Siamese Fighters attack Guppies?
I have a question about Siamese Fighters. Is it true that they attack other fish that also have long fan tails? For example: Do Siamese Fighters attack Guppies?
yes, this indeed happens. Apparently, the Siamese Fighters sometimes mistake other long-finned and colorful fish for members of their own species and attack them. This may be fatal for the physically far inferior Guppies, therefore it is advisable not to keep at least long-finned Guppies together with Siamese Fighters.
