They might have trouble with their herring or have gone to sea what Waters waving at ......they could have even gone for a swim at the local pool...... Just saying......???? ????
Well ,I hope I don't Flounder as there is always a Plaice to Skate about answering fish Questions......I'm actually a Dab hand at it ......and quite Sole less when it comes to fishing for compliments as Bill Fish will confirm ....:)D
3. Try "calling" them with food. They are worse than dogs when it comes to food. They are voracious eaters. But if you "call" them too often they will overeat and die.
You need a bigger tank. A 55gallon is easy to take care of. Also when setting up you need to leave it empty (no fish) for about a month to get the water right. The test with a cheap fish. But little tanks are fish killers. The water messes up to easily.
