My 29 gallon had ammonia spike almost a week ago and its already resolved itself. Is that common or am I crazy?
HI Shay, you will have spikes, the question is what caused the spike. and is the cause still in your tank. many times we can do some maintanence of some sort and cause what is called a minI cycle. so, no your not crazy. more details of what you might have done to the tank leading up to the spike may be helpful for us to help you further.
I meant I skipped cleaning it *Facepalm* The really weird thing is the betta, I thought he would be affected like my gourami who passed away sadly, this morning. I managed to save two platy's I bought earlier and put them in a 2.5 gallon "Hospital" tankI would just watch it daily, if you get any ammonia, do a water change of about 30% using a water conditioner like Prime. and I am not sure what you mean by skipping a cycle. can you elaborate.
I thought that was what you meant, but thought I would let you clear it up. at that point I would have done a 40-50% water change, then another 40-50% in another 3 or 4 days. weekly water changes are always recommended, but if you forget I don't see a reason to do 100%. again, I would monitor your ammonia level and do water changes when need until it re-establishes itself.
Don't be too hard on yourself, we all learn from our mistakes. I have lost more than 1 fish in my time as well.
