Stocking ideas for a new 20 Gallon Long


I have been going over stocking ideas in my head for a few days for a planted 20 gallon long I just started. It will be heavily planted with moderate Co2 and medium-high light plus a moderate amount of floaters. The tank will be over-filtered, but with reduced flow through an elongated spray bar.

Here is what I have so far:

10x Celestial Pearl Danio (Max 3/4")
04x Female Amano Shrimp (Max 2")
06x Pygmy Cory (Max 1.3")
06x Ember Tetra (Max 3/4")

I am trying to keep everything as micro as possible. I can reduce the CPD's to 6. I only ordered 10 because the were cheap and were being sold in 10 packs plus I like to order double just in case of transit deaths. I probably don't need to reduce though as I don't see them taking up much space or bio-load.

I was originally worried about what fish I would pair with the CPD, since they seem to be a docile/timid species, and ultimately decided on Ember Tetras. I was also debating going for micro rasbora (Chili, Dwarf, Strawberry, etc) instead of the Embers but I liked the color of the embers better overall.

Is there anything I am overlooking?

Pictures are not mine, just using them for a color reference

If for some reason you go with less CPD then I'd up the corys. They are sooo tiny. I have some in a 46 (transients from a 20 tall) and I have 3. 2 love each other and constantly school. I guess the other is ok being by itself. I will eventually get more when my 55 is set up and half of my fish get xfered. I hoped they would school with my dainty (hasbrosus spelling?) coreys but they don't school but who knows if they don't mind the company. CPD's are less than an inch and are very shy and timid so I'd imagine that your stocking would be ok with 10 cpd, maybe 9 corys and some tetras. I don't know the size of the tetras. If neon size maybe 7?\


Please note that the shrimp are about 0 bio load so I didn't include them in calculations. I only used what I would feel comfortable with myself.

What exact filtration are you going with?

Yeah, shrimp aren't that bad in terms of bio-load, but my Amano Shrimp are all female and full sized (roughly 2 inches each). I see them crawling by with 2 inch poop noodles attached to their tails all the time. Not really sure how to account for their bioload.

I will order 10 pygmy cory cats and keep whatever survive USPS handling. Hopefully all 10. I believe the Tetras stay under an inch, but I am still up in the air on tetras or micro rasboras.

For filtration I will use an AC70 HOB and a Sunsun HW-302 since I have those sitting in the garage already. Should be plenty of filtration.

Those pygmy Cory's do look like pretty cool fish. I have other Cory's but they all have gotten big and fat (3-4").
I may up my Pygmy count later, but I just ordered the 10 Pygmy Cory's along with 10 Strawberry Rasbora (Embers sold out over night). I already order the 10 CPD yesterday. If anything, I will probably increase the CPD count if I deem I have the room. 30 fish under an inch and 4 Amano should be a good start. Hopefully the rasbora and CPD mesh well together. time will tell. If not, either should be easy to give away.

If the Pygmy's stay under an inch, everything in my tank will be under an inch except for the Amano.

Everything has been ordered. I ended up getting the following shipped.

11x Ember Tetra's (Hyphessobrycon amandae)
10x Celestial Pearl Danio's (Danio margaritatus)
10x Pygmy Cory's (Corydoras Pygmaeus)
10x Green Tetra (Microdevario kubotai)

Only thing I am worried about now is bio-load. Everything is really small, so hopefully it will be fine.

Test your water almost daily and do water changes since you're adding them all at once. While they're not big fish they'll still create ammonia levels higher than a cycled aquarium could handle right off the bat. It'll take up to a week for bacteria to populate (maybe longer). I've always added slowly but within a week or so everything is hunky dorey.

I used bottled ammonia to cycle and have my tank processing quite a bit daily. They should be okay. I will definitely monitor daily, thanks for the tip.

I received both of my online orders of fish today.

The order with: Ember Tetras, Microdevario Kubotai, and Pygmy Cories arrived perfectly.

The second order from Ebay with: CPD's arrived with all 10 CPD's dead in a dry bag. The bag sprung a leak in transit... The seller will be shipping 10 more on Monday.

Here is the unboxing video. Please ignore the music, my 2 year old picked it out. I didn't bother posting the second unboxing since it was all negative.

Video of the fish swimming around the tank just after adding them. Colors are already popping in only a small duration of time.

Pictures are from a few minutes after placing the fish in the tank. Night lights are on so the fish can adjust. Hence the grainy photos

Sorry about the DOA, hopefully 2nd batch makes it.
If you use Seachem Prime you can do a larger dose of it to safely bind ammonia and nitrites to prevent spikes from affecting fish. Used on the 12 g when a large batch of blyxa I got completely melted a shot up ammonia. Dwarf puffers are still alive and well, and BB colony bigger now from mini cycle.

I have a bottle I've never used. Great tip. I will use it if the need arises. Thanks
