Bettas or Gouramis, Bettas or Gouramis????
Gosh, I've had both. Beloved Phoenix, purple and flame male Betta, over 3 years, in a 2 gallon tank. I would even take him with my when I went to see my mom in FLA--ack!!! Knew his name, knew me, glided through the water with such grace.
The Three Boys: 3 Dwarf Powder Blue Gouramis. Had them since last November. Spike, separate store from Harry and Larry. And so, they hang out in opposite sides of the tank. Spike has staked out territory in a broken clay pot (love those things!) and senses when H or L nears (they have a rock pile and some big plant). He's in there right now as the other boys look for possibly overlooked scraps of food, now Harry is several inches over Spike, and Larry is 5 inches to the side--skirmish? Plays into a fake-out. Spike, however, remains vigilant.
They're a real hoot, and even tho' small compared to the other Gouramis (which I would now like to try), packed with personality. It's hard to say which species I like best, since they are so wonderfully different, plus, The Three Boys together create a completely different synergy.
Final analysis: I love them both!!!!!!!!! Or all!!!!!!!! Whatever!!!!!!!!!!!
