I just got a big flowerhorn for free about 2 days ago. I noticed is poop was white and stringy with dark brown in it. He won't eat but is fully energetic, and loves to rearrange the things in his tank. I've tried live feeders but noticed that he likes to nip at them until they die. He then leaves them alone. What should I do? Should I wait alittle? Please let me know. Thanks
