Alright you guys, I'm at a complete loss.
A little backstory just to make sure I've given all the details. This tank was originally set up at my mom's house with large cichlids. I sold the cichlids and the tank was empty besides the pleco. Filters were turned off for more than 24 hours during the process of moving the tank to my dads. Filter was set up again, same gravel, decorations, heaters, filters...etc used. From there I started adding fish. Before the last batch of fish was added the tank had been running at my dad's for about three weeks and contained 3 angels, 10 rummies, 12 cardinals, 6 cories, 2 kribensis, 1 pleco. The next batch of fish I added 8 cardinals, 3 cories, and 8 hatchetfish.
I mentioned in a previous post that some of the new fish started dying right off the bat. Well, over the past week or so, I've lost just about all of the fish. I still have 2 angels, 6 rummies, 2 kribs, 1 pleco, and 7 cories, but have lost all of the rest, including all cardinals and hatchets.
I have absolutely no idea what is going on. I've tested the water multiple times on multiple different days with both liquid tests and test strips. Results have come back 0 ammonia, 0 nitrite, 10 nitrate.
Yesterday I thought I had solved the problem. I got the tank off craigslist and it came with the heaters. They were Fluval brand, seemed a little old, and recently started to get some brown discoloration. I hadn't been monitoring the temperature on the tank (my mistake ) and didn't have a thermometer, however the water did feel a little warm. Figuring I had accidentally been cooking the fish, I bought two brand new heaters and a thermometer.
Well tonight my dad called me and told me that the temperature has been a constant 78F and fish were still dying. From what he told me, all of the fish are now hanging out near the surface of the tank and not looking too well. Yesterday (and really throughout the whole process) the fish were swimming about and appeared healthy. Could it be possible that they're still being affected by the old heat of the tank?
I honestly have no other ideas as to what could be going wrong and am getting so frustrated If anybody has any ideas, I'm all ears! Would really appreciate any advice on the situation.
ETA: Some other possible ideas I've had below. I feel like they probably aren't what's going on, but let me know what you think:
-There's one octopus decoration in the tank, brand new. Could there have been something on it to contaminate the tank somehow?
-My dad said when he turned the lights on this afternoon, all remaining fish were still alive. They didn't die overnight but started to during the day. He seems to think it might be something with the lights?
-Something in the water that I'm not testing for and should be?
-Aggression from kribensis, though I've never witnessed any and that wouldn't explain why the fish are lethargic at the surface
