No they are very active and should be in a larger tank. Doesn’t matter it is 2 inches. At very minimum I would do a 20 long as but a 40 would be perfect. If you did research then you would notice 30-55g is the recommendation.I did some research on the pygmy cherub and the strain that gets 2” and I think it could work in my tank because it’s very small
Save that fish for when you upgrade.
Honesttly the best policy to to pick out must have fish first and then pick a tank to fit after.
