So I transferred my betta (Bruce) to a larger tank (Not sure what it is it gallons, we use litre's here in Australia... I'm guessing it's maybe 4?) i dont know. But any way. I transferred all of his water, stones (without washing them) and then added 50% tap water (conditioned with dechlorination solution which I have been using in his water since I got him a year ago) the first day, then 50% the next day tap water over 2 days because that is the advice I was given from the aquarium. He has a heater, the thermometer is sitting on 24 degrees celcius, and there is also a filter in the tank.
This has been set up for about a week. He was loving the tank, all the new things. Until, day 3 I noticed he started becoming lethargic. Day 4, wasn't eating... I went to work and came home. I tried to see if he was hungry again, he tried to eat but regurgitated his food.
Day 5 he was even worse, in the morning when I woke up he was laying flat underneath one of his hiding places. I took a water sample into the aquarium. The PH levels were fine. The ammonia and nitrate levels were not. They informed me to do 15% water changes every 3 days. Is this correct? They also told me not to feed him for 3-4 days.
Is there anything else I can do?
He seems to be picking up a bit.
He is swimming around a little bit more.
His coloring has faded a lot, his fins seem torn.
I feel so stupid, and mean. I had no idea about cycling a tank until now. I know to do more research in the future, but am just unsure weather to believe the people who actually gave me the advice which got me in this position... Some websites advise to do more regular changes so am wondering if anyone has experienced this before with a betta?
