125 gallon Southeast Asian River Setup

[Kenneth]

Hey guys, I just recently bought a 125 gallon tank second hand with an Eheim canister that's supposed to be rated for a tank this size(we shall see soon enough!). I was going to make a High-Current SE Asian river system, and already have the undergravel manifold for the directional flow plumbed and ready to rock. I was going to place 3 medium- high powered powerheads for the output. My desired stocking list so far is as follows:

1x Schistura cf. balteata

1x Schistura savona

1x Myxocyprinus asiaticus

5x Barilius pulchellus

1x gastromyzon punctulatus
1x gastromyzon ocellatus
1x gastromyzon borneensis
1x gastromyzon ctenocephalus
2x sewellia lineolata
2x sewellia elongata
12x Corbicual sp
5x Atyopsis moluccensis
I know I know Corbicual Sp. isn't a native to the region but I figured they may provide some cleaning services.
Anyone see any problem with compatibility they may want to let me know about before I start setting up the system? I am also open to suggestions.

I love the focus on native species, well done work indeed. I think my only advice would be to scratch the clams, I have never seen them work out well in a clean and well filtered tank. They just seem to die off slowly and are difficult to locate, thus becoming nitrate factories while they rot unseen.

I have seen that the hillstream loaches have bred in aquaria similar to your setup, but they are notoriously hard to sex. Perhaps a bit larger group might give you an advantage with numbers and buying from a single source helps to guarantee they are all the same specie/subspecie.

Good luck, I have thought about something similar and would love to see what it looks like once it is set up and running!!!

Ah! No one wants rotting clams stinking up their substrate, I probably will take them out. As for the hillstream loaches, I would like to keep more, but I just wasn't sure how my bio load would be with the banded hi-fin shark and the danios. I mean i'm sure I could keep a few extras of each hillstream in there being such a large tank, but that hi-fin can get pretty big... I am going to set up my unused 60 gallon show with spare/interchangeable rocks near a bay window with a low powered filter to cultivate tasty algae for all my fishes, there certainly will be a need I am sure.
