i just got home from work and my tiger oscar was swimming around with like a film of bubbles around the underneath of his body and some scuff marks. as i came up to the tank, he started swimming around and they came off. are they bad??? was he attacked? were they eggs? i have an albino oscar in there with him/her and they've been inseparable since the day i got them like 10 months ago.
in a related but unrelated event, my flowerhorn looks like he's starting to throw his weight around and the oscars are 2 of the biggest threats to his reign of power. it's a 150 gallon tank which they're using a 100 gallon section of which i thought would be big enough to house the specimens together without any problems. i know flowerhorns get mean but i figured i gave them enough room to manage. is he just gonna get worse and kill off the whole stock?
