HI everyone, we have a she betta here for almost 1 year now, she was thriving until now. Reorganized her tank with a new substrate (last one was sand but after one year of cleaning it ran over) now we have put river stones.
She started spitting her pellets and started spending long periods of time in the bottom, not moving at all. Tried 4 different pellet brands, but no success.
Paramethers:
5 gallons tank.
Temperatura fixed at 84F (29C)
Filter
Amonia: zero
NO2, NO3: zero
PH around 7
Yesterday she ate a pea, and accepted artemias.
Her drastic behaviour change concerned us. Any ideas?

She is likely being picky, get some live food or any treats (frozen, freeze dried, etc) and try that. If she refuses live food then you have a problem.

Keep a watch on the ammonia level. Changing up substrate eliminates a lot of benificial bacteria, not to mention releasing pollutants into the water column.
Hold off feeding for a couple of days. That should improve her appetite.

I also recomment retesting the ammonia, because I can't imagine that in a tank without plants, even if the filterbacteria are established and there is only one fish, the NO3 levels can be zero.

Do you test the parameters yourself?

Are you able to lower the temp to 80-82 degrees? I feel like 84F might be a little to warm and could be making your betta uncomfortable.

Good evening everyone, thanks a lot for the replies.
Since we changed substrate we've been putting Overnight and Oceanblend to the tank.

She is behaving weird.

BEFORE: Active during the day and never refused food.
NOW AFTER THE SUBSTRATE CHANGE: More active during night, lazy during the day, and started chewing and spitting food.

It's been 4 days now.

Got back from work and made a round of measurements, also data.

I have also gathered some info that can help

Do you vacuum the substrate or just dip out water?
> Not so often, only superficially.
What additives do you use? What brand of conditioner?
> Seachem Prime and Seachem PH Regulator

Water Parameters:

What are your water parameters? Please give exact numbers. If tested by pet store please get exact numbers. "Fine" or "Safe" won't help us help you. Important: Test your water before the regular water change; not after one.

Ammonia: 0
Nitrite: 0
Nitrate: didnt have the test
pH: 7.0
Hardness (GH): SOFT (1 drop already painted the resul t)
Alkalinity (KH): 3ºdH

Symptoms and Treatment:

When did you first notice the symptoms?
> after the substrate change which we did with using 60% of the old water, with 40% of new water. Two days later we did a 10% water change. In the same day, after we changed the substrate, she started chewing and spilling the food.
How has your Betta’s appearance changed?
> no apparent changes so far.
How has your Betta’s behavior changed?
> she became quieter and lazier during the day, however, if you show her the food she comes right away, but chews and spits.
Is your Betta still eating?
> most of the times she chews and spits, and rarely she eats only the first pellet.
Have you started treating your Betta? If so, how?
> yes, we did a salt bath and added Stress Guard to the tank
Does your Betta have any history of being ill?
> when she arrived, in a small betta tank (7 liters, no filter, no heater), she was quiet and didnt eat. We gave her a salt bath and changed the tank to a 4 gallon tank.
How long have you owned your Betta?
> 1 year
Was he or she ill or suffering some sort of damage when purchased?
> we are not sure, but when she arrived we put her in a medic tank with icht and broad spectrum medicine, even though she didn't have any appearing disease.

I'll buy a nitrate test today and post the results.
Put back her original tank setup (a tree trunk with a cave) and now all she wants to do is stay inside the cave.
Do you think a betta behavior can change that much just from day to night?
