I started with luncheon as I got my worms from Alanmin4304 and that was what he had been feeding them but they are now chowing down on southern grain McKenzie bread :roll: . They can plough through half a thick crust in 3 days or less. I think I might need to split mine too as I think I now may have too many in the box.
Without something buffering it, the pH will just swing wildly if you add stuff like pH Up or Down and this will be worse for the fish than a steady but high pH. Leave it as the fish seem OK. Driftwood will drop the pH a bit, as will a bag of natural peat tucked behind a rock or in a filter.
Pinching filter media from an established tank is an excellent way to help the bacteria.
As to photography, as much light in the tank as possible, turn the room lights off, use a tripod or sit the camera on something solid.
It's always exciting to see your first fry. Hopefully you will find more tonight. Not to worry if you don't though as you don't want to be over-run with them.
Nice driftwood. If I may make a suggestion, I would move the left (as you look at it) end of the driftwood back a bit (if you can) and/or swing the right end a little more to the front so it is on a bit of an angle. Make the tank look a little deeper.
When you buy a test kit you use a sample of half the little test tubes provided so you only need a small amount to take to the lfs. Got any old film canisters? Half fill one of them and it will be plenty.
What sort of gravel do you have? When we first started fish keeping we chose a lovely deep reddish aquarium gravel from the garden centre (don't have any lfs here). Our pH kept going up to 8.0 and we couldn't work out why. Turned out the gravel was meant for Afrikan set-ups and was designed to raise the pH! The shop assistants had no idea :roll:
A high pH is better than one that is going up and down like yours is as a result of all the water changes.
