New filter

Peformed a 20% water change and fitted the new filter. Apart from that, the male Guppy continues to hide and the female Panda Cory isn't moving much, but I'm away for most of the day, so not able to watch them! The first time I've left the tank with fish in it!

The new filter is so powerful we've resited it slightly and angled the outlet well away from the babies, but I'm wondering if I can get away without the air curtain now - at least when I'm at home! Maybe just save it for when I'm not there to watch what is happening. I'll switch it off on Monday and monitor the levels.

Maintenance - 20% water change; new filter.
