Help with brand new betta_newbie
We purchased a male veiltail betta Sunday afternoon at a bigger petstore. We also purchased a 1 gallon gravel filtered tank. WE rinsed everything with water included the tank, castle and nylon plant, pretreated the tap water with water conditioner they reccomended and waited about 4 hours before putting "fishee" in his new tank (transferred with a net). After about 2 hours, we fed him some Whartley Betta pellets (spelling may be wrong... this was recommended by the store employee), and he did eat 2
He was fairly after till 9pm, when we turned out his light and wished him good night. This morning we noted he was going in and out of the castle and somewhat active. Temperature has been between 75-77 degrees all day ( there was a big storm that came through tonight though)Around lunch time, the fish is merely lounging at the top of the tank, not doing anything. Occassionally he will take a surface breath and even less frequently move about the tank. He did not eat the pellets offered to him, nor did he try a piece of shelled thawed pea. His front fins look withered
We did a partial water change this evening-- ~ 4cup pretreated spring bottled water (we thought maybe hard water was a problem). The fish looked like he might have perked up, but now is just jerkily swimming then falling to the bottom of the tank. He doesn't appear to be breathing through his gills. He's definitely not looking good.
This is our first fish-- what have we done wrong to make him so unhappy/sick in 1 day?
Thanks for any suggestions.
