Betta fish is not eating and being lethargic?

Hi everyone,

My betta has been very lethargic over the past 2 weeks, usually staying in one corner of the tank and staying at the top. He will move his fins once a while to shift a bit but then go completely still and not respond to my voice. More recently, I have tried to feed him flake food (which he previously loved and ate instantly) but now he just simply does not eat them. It's almost as if he cannot see them, even when they are floating right next to and above his head. His eyes are not cloudy or white.

I went to PetSmart twice over the span of two weeks and I have tested my water quality and they have said my ammonia levels are 0 and the water conditions seems to be fine. I still have been doing frequent water changes with water conditioner just in case daily. He was in a 3.5 gallon tank with a filter by himself until yesterday and I have moved him to a smaller quarantine tank for the moment right now. The tank does not have a heater but our place is at room temperature.

I have had him for 2 months now and there was no issues previously. Tank has been cycled for a while now.

I have used BettaFix and PimaFix along with aquarium salt which didn't really change his behaviour so I am at a loss on what to do next. I have included pictures of him below in his quarantine tank. Please please if anyone has any suggestions or see anything wrong with him, please help me help my little guy out.

 

What temp do you have this tank at? I would stop doing all the medications if you haven't already. Medication can really take a toll on fish and treating for too many things too quickly can be really hard on them.

Hey,

Water temp is at 30 degrees Celsius. I've stopped bettafix and pimafix for this week and am just doing daily water changes. I am just worried that he hasn't really eaten for the last three days and just stays still at the top of the tank.

When I go to change water or if there is a vibration in the water, he does seem to move around and explore for a bit so is it possible his eyesight/smell is going away and that's why he isn't freely exploring and can't find food?

 

That water is a little warm for him it may be a good idea to bump it down a couple degrees and see if that helps. What all have you offered him in terms of food?

Okay, I'll try to keep it more room temp when I do a water change. I have been feeding him flakes since I got him and he seemed to like it.

I've tried freeze dried bloodworms before, when he wasn't sick and he didn't eat those so I went back to the flakes.

 

Was he in the 3.5 gallon by himself? If so, why are you quarantining him?

Yeah, he's always been alone since we got him. I just didn't know if there was an infection in the tank/on the decoration so its easier for me to help keep the tank clean.

Does it look like he has any fungal infection such as cotton mouth, ick or velvet? It doesnt look like it but I'm truly lost on what my next steps are. He is still being catatonic in the quarantine tank and ignores the food.
