I was doing a water change earlier and me being an idiot forgot to throw Prime in. Then about 20 minutes later I noticed all my fish gasping for air and then some of them were laying on its side. Quickly added prime, lowered the water, threw an extra XP3 on there to create more current and oxygen. Dosed a couple extra caps to treat as if ammonia spike.
1 RTG, 4 Dats, and a Endi in the tank. Thankfully the RTG looks better and is swimming around now. 2 of the Dats are semi recovered with some movement, but two of them are still on its side on the bottom and breathing pretty heavily. Any suggestions on what can be done? It's been about 4 hours since it's happen and I'm just hoping everyone recovers. So mad at myself for this stupid mistake. If I could sacrifice a fish it would be the dats instead of the RTG, but I'm hoping I can save them all. Any suggestions would be greatly appreciated. Thanks!

Hoping the last dat in the tank can make it. At least aro seems more active this morning so that's a relief.
