Hello! I'm new to this forum. If a topic of discussion already exists...please feel free to merge it with the existing one!
Well I purchased a new male Siamese fighter a couple of days back! I told the shopkeeper that I have 2 sharks and a pair of gold fish in my tank already and asked if it would be safe to keep the betta along with them. He said its 'perfectly' fine. For the first few days it kept hiding behind the filter and didn't exactly move around freely but then after a day or two I noticed my goldfish fell sick - it almost stopped taking food, and then after sometime it died. I supposed shark might have attacked it. Since I noticed it was WOUNDED and its eyes were eaten...it was weird :S But little did I realize that it was the fighter which ate the goldfish indeed...after sometime it started chasing the other goldfish as well. So I moved him to a new tank.
Aren't bettas compatible with goldfish?! I know two male bettas cannot be kept together but I have heard its absolutely okay to keep one betta in a tank with other fishes. Sorry if it doesn't make sense...I'm relatively new to fish keeping. Please helpppp! I'm thinking of moving the gold fish to the other tank, so that I could keep the betta with the shark. Are they compatible with sharks? Or are they generally aggressive towards other breed of fishes as well?!
