I have 5 glass fish, a golden apple snail and 2 bala sharks. Unfortunately, one of the bala sharks came down sick this sunday. He's flapping on the bottom of the tank for days. He can't swim straight, he can't swim right side up, he keeps hitting everything an he's on the bottom wiggling his fins looking very distressed and pained. It hurts me to look. I've been medicating the tank with antibiotics and antiparasite pills but he's not getting any better. :-( I've tried dropping some peas in there to see if he'll take the bait but no go. Dunno what to do :-( The other bala shark is his best friend, and would probably be saddened if he doesn't pull through.
