Pair of Jewels in this tank?

I posted earlier about possibilities for my 20L. Well, it's just about
done cycling and it's time for fish. pH is around 7.3 (right outta the
tap). I think I'd like to go w. a pair of Jewels (as posted in the
other thread, thanks Amateur). This tank look ok for them?

Looks good, but you need more hiding places. get more rock to make caves.
one of them will chase the other and kill it if they cant hide. I have 2 of
em in a 60 gallon with a 7.5 inch red devil. he tries to get em but they
are smart and fast and have many hiding spots. Enjoy. jim
