One or two more visits to the store should finish my tropical tank. I filled out my Cardinal Tetra school up to 12. They seem happy. I got 3 Sunburst Gouramis to give the tank a splash of color. Next week, I hope to get 10 to 12 pygmy cories and maybe a couple of Sparkling Gouramis or Croaking Gouramis. Actually, I am strongly considering going to get those Croaking Gouramis now. Should I? I am pretty sure it was one male and one female. They were a bit more lively than the rest of the fish in my tank, especially the other 3 Sparkling Gouramis. What do you all think?
