I don't usually post questions in this section anymore, but I figured since I'm looking for unbiased and arbitrary opinions, along with any tidbits anyone happens to know about the fish, I migth as well. I'm going to soon be revamping one of my ten gallons, as a new home for one of my other fish (we'll get to that later). I wanted to turn it into a semi-community tank, but it's gonna have some less-common fish in it. I basically just wanted opinions on which of the two species I'm considering, folks would choose. Both are 100% acceptable tankmates for the fish I already have, both have comparable bioload and group requirements.... the catch is that one of them is going to be really, really hard to find. I'm considering the following: Daisy's Ricefish - http://www.seriouslyfish.com/species/oryzias-woworae/ (this is the one that will be insanely hard to find. I may have to import wild specimens from asia, and that's IF I can even find them. good news is, I know who to ask LOL) Dwarf Pencilfish - http://www.seriouslyfish.com/species/nannostomus-marginatus/ (currently available at The Wet Spot) The tank will be well planted, as always, with plenty of wood and rockwork for hides. I'm planning several small tunnels made of PVC an anchored with rocks. I can modify pH to meet the requirements of the fish, so that's not an issue, even though they're both sensitive to pH levels. The following is important only for aesthetic reasons - the "centerpiece" fish in the tank will be a female betta. I'm not interested in hearing about bettas in communities. I am usually the one giving those speeches lol. But, this particular female is community friendly. She's also sterile, so she can't be used in my breeding program. She's a very red koi coloration with black, white, and some irid specs. I definitely want fish that will compliment her, both in demeanor and in coloration. For reference, I've included a video of Polly and Neo, her ex-husban, for those who haven't intermet her yet The most important factor in choosing a species is going to be whether they will nip her fins. She's community friendly, but let's not kid ourselves, she's still a betta. Pencilfish are common dither fish for shy SA cichlids, so naturally I assume they're not going to be bitey with her. Ricefish are common among the same habitats as wild bettas and I've never come across anything stating they tend to be rivals, so my mind immediately goes to them when considering tankmates for bettas. As far as I know, Ricefish are completely peaceful, so likely will not be attacking my Polly. Anyway, given that both species are so... alike.... just based on looks, what would you choose? [video=youtube;gtJHPPB-IKo]https://www.youtube.com/watch?v=gtJHPPB-IKo[/video] (hopefully you can all tell the difference between the male and female... lol). Polly has colored up considerably since this was taken. She has acquired black lipstick, black specs, 2x the red over her back, and a few speckles of iridescence here and there. Edit: Just found Mekong Ricefish for sale at The Wet Spot. http://www.seriouslyfish.com/species/oryzias-mekongensis/ My main concern with this species is that Polly might look at them as a yummy snack. She's quite small for a betta, and she's full grown. But those are REALLY small ricefish and not very deep bodied at all. Opinions?
