There's A Weird-Looking Spot On My Male Tiger Barb And I Don't Know What It Is. It's Not Orangey Like It Should Be. He Wass Fine Overnight, But I Don't Know What It Is And I'd Really Hate For Him To Die Cuz I'd Only Have 1 Fish Left.
Ok, It Sound Gross, But I Think Its Clear. I Didn't Notice Anything Bad About The Water Quality:
pH: 7.2
Ammonia: 3.0
Nitrite: 2.0
Nitrate: Unread(Yet)
The Nitrites Are Starting To Rise And The Ammonia Is Starting To Drop(In The Cycle).
i would be very concerned if ammonia or nitrite got any higher at all. (nitrite is very toxic to fish more so than ammonia) I would suggest doing a 30% water change now and then 20% in another couple of days to lower the concentrations of nitrite and ammonia.
I highly recommend using conditioner for your tap water. It gets rid of chlorine and neutralizes chloramines and other bad stuff in your water (heavy metals).
I Changed Some Water(Then Dechlorinated It)And Added To The Tank. And Also I Dechlorinated The Water Before The Fish Were Put In It, Do I Need To Dechlorinate The Entire Tank Again?
The Nitrite, Ammonia, And pH Stayed The Same Overnight. The Fish With The Spot Is Acting Like He Would Without The Spot. I'm Actually Wondering If It's Just The Way The Particular Fish Was Made, But I'll Be Supplying Extra Care For This Fish Anyway.
You only have to dechlorinate when you add new water from the tap, and only that new water needs dechlorinated. If you have a two gallon tank and add one gallon of new water, add enough dechlorinator for one gallon only. That water won't need decholorinated again ever.
I SWEAR, These Tiger Barbs Should Be Called Pig Barbs. They Eat Three Times A Day And All The Food Is Gone Within 1 Minute. They Live On Bloodworms And Fish Flakes.
I don't know how much you're feeding them or how much tiger barbs usually need, but be careful not to let them get obese. Fish can overeat too. It's not in their nature to turn away perfectly good food.
