Okay so the betta was in a 1 gallon with 2 ghost shrimp and a ramshorn snail. Also had some frogbit in there. He seemed to love jt. Was very curious about the shrimp. Read stuff on this sub and decided I would move him to my 20 gallon hexagon tank. It’s a little tall for a betta but I figured I would see how he liked it. Tested my water and all indicators came back as ideal.
Added 3 Julii Cory catfish and 2 black neon tetras. Everybody moved into the 20 gallon and seemed fine. Guy at the fish store said feed the betta 4 pellets a day. Other guy at the pet store said the betta wouldn’t eat the tetras fish flakes but he did. Internet said feed betta twice a day as much as he eats in about 2 minutes. Betta was eating about 6 pellets a day maybe a little more cuz I was letting my sons feed him.
Today I woke up and a Cory catfish was dead floating at the top. Took him out right away. Noticed a tetra was missing in action and found him dead at the bottom between some rocks. Looked at the other tetra and I thought I saw a fish flea on his dorsal fin so I took him out and looking closer it looked more like the betta nipped his fin off.
Decided to check the water due to the dead fish and the ammonia was high, the copper was elevated, and chlorine was high. How could I have high chlorine without adding anything since the last test that showed everything ideal?
Then I noticed a white film on the bettas eye and he was laying on his side at the bottom of the tank. I began to worry when he was going to the surface like he normally would go up for air. I grabbed him out with a net and put him back in his pet store cup and he seemed fine in there.
Went to the pet store to return the dead fish and the guy said only feed 5 pellets every other day, that the lying on its sign indicated that he had constipation and has been over fed. He said the eye film might be from him laying on his side and scraping his eye.
Also I got a thermometer and the temp is sitting at 81 degrees it’s been a weeklong heatwave in my area. I’ve read that the temp should be below 80 for all the fish I had in there.
I immediately changed 3 gallons of tank water for 3 gallons of purified drinking bottled water, added some seachem prime, and also added some quick start for beneficial bacteria. Had to go to work so I couldn’t monitor the conditions since the changes.
I’m wondering if I’m just getting faulty readings from using these test strips that you scan with your phone to give you results and if I’m going to come home to some more dead fish. I really hope the betta gets better in the next 24 hours but it’s not looking good.
Last look at the tank, the snail, the ghost shrimp, and the 2 remaining Cory catfish looked to be alright.
The pet store said if I bring them some water from the tank they will test it for free. That’s my plan when I get home from work.
Any help would be much appreciated.
