So one of my guppy/endler hybrids is acting strange. He was swimming very slow and hanging out on the gravel. He is now swimming at top but still slow and kinda hanging his tail lower, so not horizontal. His gills look a little flared and he I really red around the mouth. Water params are all 0 and pH 7.5. Maybe he did it fighting? No one is bothering him at all now.
