Well the bubble rate isn't as low as I was hoping but the new diffuser is doing a good job, getting a nice lime green dc. But the big news is two tester fish from my other tank are doing really well with the fairly high co2. I am happy to add the rest of my 15 copper harlequins at some point this week. Next thing is to source some amano and red cherry shrimp, try to catch my other fish: sterba's cories (need more), ottos (need more), threadfin rainbowfish (need more).
Once all these fish are out of the small tank (65l) I may set it up as a softwater breeder for some liquorice and chocolate gourami.
I have also set up a nephrolepsis fern in some orchid substrate (bark chippings and moss) in a plastic box that had some chocolates in, on the back of the tank, I'm quite proud of it:
Plants generally doing pretty well, still some old ragged bits but new growth is quite lush.
I trimmed the flame moss (made a right mess) but I'm still not very happy with it. Considering trying spiky moss, I want a taxiphyllum species so it has a chance of attaching. Or I could use fissidens/riccardia but I think a dry start is best for even coverage with these, and they are slow growers.
Just made a little skimmer guard:
That's about it for now. Slowly but surely I am sorting this tank out, with the addition of livestock I hope I can finally begin to enjoy and appreciate this slice of nature.
