(Part 2) Best aquarium fish feeders according to redditors

You're probably not going to find real quantifiable data like that because there are so many factors including growth media and I'm not sure it scales up and down linearly.

I have:

• a 10 gallon tank; with two goldfish; a water jet; airstones; automated feeders; and an eheim filter- supporting two house plants

• another 4l0L (10 gallon) with two or three yoyo loaches (rescued); a panda catfish; and an algae eater- that supports a large windowsill planter of growth media holding mint/shisou/thai basil and has a eheim filter for extra biomass and 2 water jets; airstones in the tank and biomass area; and an automated feeder

• Finally an outside setup with 150 gallon tub with 5 goldfish (rescued) that runs through PVC pipe with about 10 net baskets with heads of lettuce and an automated koi-pond outdoor feeder.

  These are all stable systems that have lasted about two years a piece

  Issues of any cruelty aside- this is fine as a starter/intro and you'll find that you'll likely want to upgrade as things work out- mostly because small systems are a lot harder to take care of.
  
  The thing with goldfish is that they put out a lot of ammonia (so in a small tank ammonia poisoning might be a thing) and the size of the container tends to cap their growth. But I wouldn't sweat the fish thing too much because a few of them might die due to the tank being new (although goldfish are extremely hearty) sketchy source: http://www.firsttankguide.net/newtanksyndrome.php
  
  It's hard to tell you straight away about how many fish etc because this aquarium system looks fresh and not yet cycled- ie. your aquarium probably doesn't have it's fill of microscopic plant life living in it and in the growth bed material you are using. Be aware you'll likely need to treat the new water you add into the tank. (chlorine remover etc) and that adding new water will have a relatively large effect on your tank due to it being compact. sketchy source: http://nippyfish.net/2009/05/27/cycling-a-small-aquarium/
  
  This means that you'll need to watch the amount of food you feed your fish carefully.
  
  100 grams of fish food will generally support about one square meter of plant life.

  The great thing about what you are doing (cycling, establishing your grow bed as a bio filter) is that if you start a new tank, you'll be able to use this water and material to start out a larger tank faster (largely what you did by getting some of their gravel).

  Nice tips/ways to scale up or automate things to make your life easier:
  
  
• Petco often has dollar-per-gallon sales and there's usually tons of tanks on craigslist etc if/when you decide to scale up.
  
  
• Automatic feeders make the process less hands on:
  ie. http://www.amazon.com/Automatic-Fish-Feeder-AquaChef-Batteries/dp/B004249KFG
  
  
• A water pump to run the fish water through the growth media might do your tank very well and are quite cheap, this one is 8usd: http://www.amazon.com/Patuoxun-Submersible-Aquarium-Fountain-Hydroponic/dp/B00EU74MJY/
  
  
• Additional biomass:
  
  
• This filter (15usd) might add a little additional biomass, which makes your aquarium a little larger and helps breakdown the ammonia etc: http://www.amazon.com/TM1250-Aquarium-Internal-Power-Filter/dp/B00176GKM8/
  
  or
  
  
• (25usd) http://www.amazon.com/Aquarium-Rapids-Canister-hang---tank/dp/B000YJ0M1E/
  
  
• Again waterflow (helps with algae) then something like this is about 9 usd: http://www.amazon.com/Submersible-Circulation-Maker-Water-Aquarium/dp/B009YEEW2K/

We use automatic fish feeders for our fish, like this.

If you are having someone else feed your fish, it might be helpful to use small cups (like paper bathroom cups) to divide up the amount of food that is supposed to be fed each day. You could also use a marker to mark the date you would like each cup to be administered.

So sorry for the loss of your fish.

If you want there is a ~$20 automated feeder you could set up.

Might not be super reliable but it will at worst skip a feeding.

You have to adjust it and dial it in a little but you can choose how much they dispense each time and how often they dispense it.

I've used the Rena automatic feeder for about 4 years now. The main reason I bought this one is because it has a light sensor you can turn on so that it doesn't feed at night and it has a small heater built into the drum so that the food stays fresh.
