Yea will get one at the earliest, as I said after the water changes and other steps which I followed as you guys suggested, the fish was so active and eating properly, again in 13 days of time it has become lethargic and started showing all irregular symptoms.You need to get your hands on a bigger tank right away. This fish will grow massive and can gain 100cm eventually. You will need a tank of at least 6-800 gallons for this fish. As i said nothing personal on you but you woll have to listen to what people here tells you to do to get this fish to survive.
