Hi all. So I’m a newbie fish keeper and after cycling my tank for a month I had stable parameters of pH 7.4, Ammonia and Nitrites at 0 and Nitrates at 10-20. Temp set at 80-82. 9gal fluval flex. I placed sponges over the pump to slow the flow but still have some moment. Tank is planted.
today our female betta died. She had been refusing the food (Omega One Betta Buffet Pellets) but was seeming to eat the copepods in the tank and was interested in the “Dial a treat” dried food.
I checked the parameters this morning after we removed her. It’s still pH 7.4, Ammonia/Nitrites 0, Nitrates 10-20, temp 82. We also have a nerite snail in the tank but it went inside the cave decoration and never came out. I’m going to investigate if it’s still alive once I change the water.
My question is, what could’ve killed our fishy? She had “zoomies” yesterday according to my husband so she wasn’t lethargic. I noticed she looked a bit bloated and was getting white under her chest/belly area. I worked 12 hr shifts the last two days so I couldn’t do any interventions. My plan was to buy fish medicines today but it was too late. I have included pics of her from last Wednesday and then today.
Also, what should I do to make sure the tank doesn’t have any infection in it? Should I remove the carbon filter and dose the tank with medicine after a complete water change? I’d hate to start from scratch but understand if that’s what needs to happen. Thank you so much for your help!
