So today I've come home, looked at my tank and found one of my harlequin rasboras floating at the top.
For the past few days his dark patch on his sides have been faded but I didn't think it was any cause for concern. He's been keeping up with the others and eating normally up until now.
When I found him floating, hip fins were missing the tips and an eye was missing. Is it likely the other fish might have nipped at him after he passed?
The tank parameters are all within a safe margin
pH - 7
Nitrate - 0
Nitrite - 0
General hardness - 180
Their last water change was five days ago (28/10/19) and this was from the same water source all their changes have been from, they've never reacted badly before. I feed them twice a day with one fast day a week just before their water change.
The one that died was the smallest fish in the tank. I've never seen my betta try to attack them nor have they tried to attack the betta and I've only witnessed them glass surfing when they were new to the tank and during a larger water change.
What could have killed him? I'm quite new to the hobby but to the best of my knowledge I haven't done anything that should have a detrimental effect on the fish.
