Stocking Advice 125 Litre

I would go for the sparkling gouramis as licorice gouramis are quite sensitive fish. And wait before getting the otos as you need algae to have grown first.

The CC puts your list at 92% stocked; adding an extra 2 galaxy rasboras and pygmy cories would push you to 96%, do-able if you keep on top of your maintenance.


My Hidom AL-2 arrived yesterday; it's a similar shape to the CL-6B just smaller for a 26 litre tank, and with a slightly different neck. It looks and feels a nice piece of equipment - and the plug-transformer doesn't look at though it will split easily. However, it doesn't seem quite as bright as the light that came with the tank. The old one had 24 white LEDs, the new one has 42 LEDs, a mixture of blue and white. It could just be imagination about the brightness of course since I've been using a tiny 4 LED strip since the old one broke 

Since you already have one, smaller tank running, you do know that you can use all the media from the old filter when you set up the new tank, and transfer the media and the fish you already have at the same time? You will need to keep a close eye on the ammonia and nitrite levels for several days as you will lose the bacteria on the things you don't move across eg the tank walls, substrate etc. Once you are sure you have double zeros, then just add new fish one species at a time, waiting till you have a week of double zeros before getting the next batch.

Now I know better of course so I'll be getting  ammonia and nitrate testing kits to help me through.

I hope that was typo, it's nitrite you need
