i was just wondering if i could put anymore fish into my 20 gal. it has been up for nearly 3 months with no problems. i have 2 true percs in there now with 2 shrimp, emerald crab, hermits, and snails. any advice? thanks!
Assuming you have good filtration and don't skip water changes you could add another small fish or two. You could do a firefish, a neon goby, or a clown goby. :happyfish
