Newly Cycled Tank. Vacation

Hello out there! I'm hoping someone can give me some guidance before I leave for a 3-day vacation tonight. I have a newly cycled tank. My nitrites finally went to zero yesterday. They're at zero today. Yay! My ammonia is at .1. Nitrates are at 6. I have a 29 gallon tank with 5 Giant danios. They are all doing great. Their color is much brighter and they seem happy. My last water change(20%) was 5 days ago. I've been feeding them once every 2 to 3 days. First question: should I do a water change before I leave? Second question : since I just fed them yesterday, should I feed them again today and then when I get back in three days? Or should I give them a 3-day feeding block?
Thank you!

 

3 days is not very long. Fish can go up to 2 months without food if they need to. A fast is actually good for them since they clean old food from their system. Also since your tank is just newly cycled I wouldn’t recommend the feeder block since they are not always the best. You can do a WC before and after. Since your tank is just cycled you’ll need more WCs until everything is going smooth

 

its to my understanding that when your tank is finished cycling you shouldnt have any ammonia or nitrites. but lets let someone with more experience reply! and also most people feed their fish everyday. and after looking that up myself that's pretty much what everyone is saying. but at the same time fish can survive several days without food no problem, but again lets see what the experts have to say about that! ive watched this thread so I can learn with you

When a tank is completely cycled both ammonia and nitrites are 0 and nitrates will show up. In a cycled tank you may have ammonia spikes if you overstock, overfeed, or loose your bacterial colony, or if your tank was not completely cycled to begin with

 

Thank you! I appreciate the advice. WC on the way

As for feeding, opinions differ among fishkeepers. Some fishkeepers will feed their fish a large amount of food, but only once a week. This simulates nature (a fish is not going to find food everyday, thus when they do they gorge themselves) doing this also helps some fish breed since they will be more encouraged to breed in times of plenty. Other fishkeepers will feed their fish small amounts daily, with a one day fast at the end of the week. Some will feed very small amount twice a day. It really just depends on the needs of your tank. Some fishkeepers may be more encouraged to do daily feeding if they keep (for example) cherry shrimp with a Betta Fish, in which case keeping a well-fed betta will deter him/her from snacking on shrimp, whereas others may do less feedings if they wish for the betta to hunt more shrimp to keep numbers down

It sounds like your tank isn't fully cycled. Before you go, do a couple water changes to lower any ammonia in the tank. After that, I wouldn't feed them for the duration of your trip. It's only three days and the fish will be fine. A feeding block is more likely to make a mess in your tank and raise nutrient levels, leaving a mess you'll have to clean up when you return and just wanna relax.
I've left my own fish (saltwater) without food for up to a week during Thanksgiving and spring break. Good luck and have fun on your trip!
