my buddy gave me his tiger barbs after 6 of 8 were killed by the shark.So far I have housed my Rainbow Shark (about 2-3 inches) with 6 glofish danios, 5 white clouds, and 5 tiger barbs.
The tiger barbs are acting funny, and half of them are missing parts of their fin, but I'm not sure if the Rainbow Shark is the culprit. He is aggressive towards them, but only when they get close to his home.
He oddly never bothers with the danios and white clouds despite them being significantly smaller than him.
What did you have before that he killed?
