Had a bit of a disaster today in the bully/torrentfish tank where the pH plummeted overnight (DIY CO2). the pH was so low that even after a 25% W/C it was still below 6 and the torrent fish were still very sluggish and breathing rapidly.

With this and a WCMM tank that had gone cloudy over the last 2 weeks, ~30% W/C every few days was having no effect at clearing it and neither was a new filter to replace the bubble one, I decided to pull down both tanks and just set them back as one.

This involved:

1. Relocating the biggest torrentfish and the two common bullies to the main tank where they wont eat the WCMM.

2. Catching the fast redfins and the now responsive smaller torries.

3. Washing all the sand/rocks to try and get rid of most of the cyano that was around.

4. Then setting it all up:

The two smallest torries (this springs returning fry) and the three female redfin bullies should be too small to eat the WCMM, except if they spawn*. This could well be an interesting mix of fish with the torries on the bottom, the bullies there about 80% of the time and the WCMM filling the middle of the water column. One of the torries is already exploring the tank and sitting in the high flow areas. At least two of the redfins are out and about as well as the WCMM

The 2x1x1 tank as 2 450 l/h filters one for flow, with only coarse sponge and the spray bar pointing along the bottom - right to left, and the other for filtration/biological.

*The WCMM males are displaying like mad and it looks like at least one of the females is responsive :bounce:

I like the tank. I am deciding on what to put in my coldwater breeding experiment and these pics are giving another point towards WCMM. :thup:

great pics!
