Hardy corals for nano tank

hockeyhead019 · Nov 8, 2017

Hey everybody,

I'm looking for some rather hardy corals to throw in my 20gal reef. I ask for hardy because of the small water column. As we all know the smaller the water column the more sensitive the system to small changes in nutrient levels. I'm looking for some hardier corals that won't melt in this kind of environment.

Right now I have a frogspawn which seems plenty happy on the sandbed.

Tank Equipment:

Nanobox Duo LED lighting set for 6 hour photo period with 2 hour max lighting
20 gallon w/ live rock and sand bottom
5 gallon bucket sump with reverse lighting and LR and cheato to combat pH swing and general nutrient absorbtion
Flow: Jaebo WP-10, cheapo Chinese power head and return pump rated at 25gpm

Suggestions are welcome! Suggestions with pictures are even better

With many corals the biggest problem is chemical warfare. If you have frogspawn, you may want to do more varieties of frogspawn or some hammer. In such a small area, favias will fight with large stingers and so will many chalices. I would also stay away from large leathers as they tend to make a mess of small tanks.

Not sure in a 20g. I have 40 and 6g along with my large system. Not sure what I would do with 20g. Maybe frogs, hammer, trumpets of many colors? Maybe some encrusting montis with acans on sandbed. What do you like?

I have a 20 gallon mixed reef. Just stay on top of water changes and you should be fine. I have zoas lps and montis

I like zoas and the colors of acans... frogspawns are awesome too and definitely on my "to get" list. Sounds like it might be a good idea to keep an eye on the spacing and make sure they aren't on top of eachother
