2 females won't be much of a problem, just give them territory to establish. Two males... well, you know how guys are. Two males will be constantly displaying, charging and chasing each other. The dominant one will pick on the submissive one when he sees the other one. At one point, I had FOUR males together in one 40 gallon tank. They coexisted...somewhat. Usually one was the most dominant and the others were submissive. But that was a tank that they had plenty of room to escape to if they needed to. With your 15 gallon being vertical, there's really not much room for one male to escape if they need to, so I don't suggest two males in a tank that small...
For decor, they like heavily planted tanks with plenty of caves such as overturned terra cotta pots, natural caves made by driftwood, places they can hide in, etc. Floating plants are appreciated because their natural habitat has floating plants with heavy plants underwater.
I"m pretty sure I've decided to do the king and pigmys for the 15 gallon column and the apistos for the 27g cube community. So that should help. I intend on putting in some rock formation caves in the 27 and more decor before getting the apistos. However, I'm not planted in the 27. It's all fakies. Real plants were going to be part of the new endevor on the next tank (the 15 for the king). Thou I could easily toss in some real floating plant that doesn't require a lot of light into the 27...
I haven't decided if I have a green or brown thumb with tank plants. Now rose bushes, that's another story... but I digress.
Okay. This probably sounds confusing. Look at my profile, I have it updated with intentions fish/plant wise. LOL
Does this sound apisto friendly or do I need to convert to real plants before adding them to my water world?
Awesome. I know where that one is and I will file this in my fish folder in my brain LOL
Hey, I saw something at Petsmart just today called a 'Dragon Scale' Betta? Some of them were marked as Crowntail Dragon Scale and others were marked as just Dragon Scale. The non-crown ones looked like they had short fins, but not quite the pleated look of a plakat (at least that's how I describe it). Any clues?
