What are your favorite dwarf / small rainbowfish?
I am looking to add rainbowfish to my 55g planted community tank. I've never kept rainbows before and am excited to get into them! I went to the fish store the other day and saw some cool young red paskai's that I am thinking of getting. I also really like the look of some bigger growing rainbowfish, especially the Trifasciata, Parkinsoni, and of course Boesemani. I feel like putting the larger growing species in a 55g isn't the most irresponsible things as getting rid of large, beautiful rainbows is probably pretty easy when the time comes. Here are my questions:
1. What are your favorite small or slow-growing rainbowfish?
2. When stocking dwarf rainbowfish like the pseudomugil species, is it okay to get say three of each or do they need to be in a larger group?
3. Is it worth it to get large growing rainbowfish knowing I'll have to get rid of them eventually? Mainly interested in their growth rate as well as if they color before reaching large sizes.
4. I currently have 3 small angelfish, a pair of 1.5" borelli, a pair of samurai gourami, and plan to get venezuelan cory's from a breeder. Will the dwarf rainbowfish or larger growing rainbowfish run into any problems with these fish?
