I was feeding my fish Hikari food sticks and while my Aros and cichlids were munching away one of my Pbass dashed towards my thermometer and smashes it...the thermometer is the ones that are glass/floats and uses a suction cup. My Pbass was actually trying to eat it! He has a cut in his lip now and he turned all black from it. Hopefully he's ok. I had to siphon all the glass out and did a small wc and added aquarium salt. I didn't do a major one cuz I just did a 40% wc yesterday. Hopefully I didn't leave any glass laying around. Now I know not to use those glass thermometers and stick with the sticker type ones for monster fish.
