So i have a 20 gallon cube with 4 fish, a gramma, a spriger's damsel, lubbock's and a red stripe cardinal, i am using a kessil(i forgot what model) and a wavemaker that i also forgot the brand and model. my luck with sps hasnt been the best. So what would be some easy acros besides the bali greens? i know ORA and WWC frags are quite good but i can't get them in my area that easily, so just some generic names and species would be good. Thank you!!!
