Good to see you back AS.
I too have slung my more solid lumps of wood. I’ve replaced them gradually with spidery branchy type pieces. It allows more water in the tank, more circulation and I love to see the smaller fish swimming through them as opposed to around them. I’m drifting over to even smaller fish these days. Probably due to the tale below.
We‘re also ploughing through one of your livebearer explosions. I spotted a beautiful light blue lyre tail male Endler in PAH months ago and he was still there the following week when MrsLurch popped in there for cat food so he was snapped up. (reads badly that doesnt it!).
After three weeks solitary she put four of her females in with him instead of the two I suggested. 140+ fry later it’s still impossible to do a WC of the female tank without inducing another 5-15 fry. Every week it’s happening.
Your last arrangement in the post above is the one to use as a starting point imho.
Aaww, thanks dude! Lovely to see you too! Any pics of that lyre tail Endler male please? Sounds beautiful! I completely understand the temptation when you see a fish like that, that really grabs you, and especially when you have livebearers already, what's one more? But as you well know, then you want to breed that one, and they explode with babies everywhere you now have to raise and find homes for... lol! I really enjoyed keeping my livebearers, don't get me wrong. And I'm sure I'll have more at some stage. But at the moment, I'm relieved that the stress of constantly raising and rehoming guppy fry has gone! Of course I say that, and I'd finally rehomed the very last fry only a couple of months ago, and now my cory population has exploded, and I'll be raising and finding homes for all of them! Adorable little guys though, super fun to watch.
I like the look and the space given by the more branchy/spike wood pieces for sure. But since I really want this tank to make the plecos happy (and maybe breed - still not sure of their gender), and with the way corydoras bumble around, I think the more solid pieces that they can all safely explore and nom on without poking out an eye would be better for these guys. I do think I want one of the spiky branches as part of the arrangement. I'm glad you also think that something similar to the one above would be good! So the spiky branch will be higher up in the tank, adding height, but not a constant crash hazard for the bumbling bronzes, lol. Final arrangement won't be quite like that, but it's a rough starting point. Planning the more branchy/spiky pieces for the upgraded pygmy 20g though!
I'm leaning more and more towards nano fish too. Even in a huge tank, I think I'd want to fill it with a huge school of dwarf cories and a few hundred chili rasbora - and a ton of plants, of course! Huge groups of tiny species just works so well, and you see behaviours when they're in big groups that you just don't see when kept in groups of six or so. Saw a good vid about that recently, might make a thread about it and tag you if you'd like. Here's the vid, I love her delight at seeing the behaviours of the pygmies, and it's been my experience too. Once my group of seven grew to a colony of 20 and above, they school around and swim in large groups in a way they just didn't before.
