What I believe was the size and force of EBH is bigger than the red hook, hence the impact force for the EBH to knock onto the glass is huge.
Therefore, provide hooks with large space and avoid to spook them is the key to keep them for long. |
Hi Nevin, I did not do anything different like wc and water parameters are alrigjt(checked using kit) and all other fishes are alright. I do suspect them knocking into the glass walls as well but I've been keeping them for over a year and once recently one died and now another. My previous hook swim like that for over 3 days before dying making me more curious as it should die within hours if it was something serious.. Guess I'll let this guy stay in my tank and hope it recovers hearing that yours recovered after two weeks.

Hi Chu, yes I know they are tough, they often bang on glass wall even I on their lights when they are sleeping (accidentally). I've been keeping them for over a year in my tank and this happened recently only.. They are quite big tho.. Above 13" or even bigger.. Could size play a part?
