- Clean your tank
It's a pretty good idea to do a nice, big water change the day before you leave. If you've been reading my articles, you have probably clued in that I think water changes are THE healthiest thing you can ever do for your fish! :) A 25% or larger water change will ensure you have lower concentrations of ammonia and nitrites, cleaner gravel and less bio waste in your tank. No matter what else, this alone will ensure the healthiest environment you can provide while you are gone. For a betta in a non-cycled tank, of course do a 100% water change.
- Change your filter
While a water change will do most of the work in creating a healthy environment while you are gone, consider a filter change if it's almost time to do change it anyway.
- Turn the light off
Unless you have live plants in your tank that need the photons, the fish will appreciate a respite from the bright lights they are normally subjected to when you are home.
- Feed your fish
Do NOT overfeed in anticipation of your absence. While there is a big tempation to dump the food in, you will only make your fishes bloated, sick and possibly constipated. Overfeeding does no fish any favors. Just do a regular feeding and say goodbye.
- Don't tell a neighbor to feed your fish while you are gone
Unless you have a fish-knowing friend or neighbor, chances are your well-intentioned care giver will overfeed and probably kill your fish. Unless you plan to be gone for more than 4-5 days, your fish will survive a nice, healthy fast period.
- If you will be gone a week or more
I don't like those feeder blocks - they really just pollute the water. Use them if you have a bottom feeder - one block only. For other fish, either use a mechanical feeder, or find that fish-knowing friend to help out.
These steps will help you see your fish alive and well on the day of your return!
