Sudden death?

[Relic]

Came home from work to find Caesar {Fish in avatar} dead. I have no idea what caused his death...He looked fine and happy last night and this morning. Checked my water parameters and everything is fine. What could cause a sudden death like that? I have some neons in the tank...should I take them out and clean the tank real good? I'm not about to dismantle the whole tank and risk killing all my plants too....should I do maybe a 50-75% water change?

I've seen your tanks and they're really nice.

Maybe your HOB type filter had something to do with it?

I know my bettas don't like the water flowing in from my 3 filters. The 3 filters are in there for testing purposes since I've NEVER used them before.

If your water tested out fine, leave everything alone.

I've seen those deltas before, & was very tempted, but I left without bringing one home.

I'm kinda glad, because I'm not sure if they can swim that well with all those fins.

I don't think my filter had anything to do with it..Its baffled so there isn't a whole lot of current. The tank he was in is CO2 injected....I wonder if that may of had something to do with it? I do have a O2 bubbler in there as well.

I don't think it was the CO2 because he could have went up for air if the water was low in oxygen. Might be an unexpected death like when someone drops from a massive heart attack or stroke. I personally would just do a large water change. Since he was not sick. I'm sorry for your loss, he was beautiful
