The week after the first three black neons were introduced I added the penguin tetra. Tetra are happiest when kept in groups, so I thought the penguins would add some company until I get some new black neons.
These are slightly larger than the neons, and they have a black stripe which continues onto the lower tail fin. However, it seems I am unintentionally going for a black and white theme for the tank! I plan to make sure the next fish I get have some more colour 🙂
The new penguins were more agressive to begin with and they settled in much more quickly and were chasing each other, and the neons, round the tank within 10 minutes. Overall they have livened up the tank and all the fish seem more confident.
I also added the shrimp (“Scampo”) a Japonica shrimp, who is now my favourite denizen. It sits behind the heater at the top of the tank disturbed when it hides. I thought I didn’t include many places to hide in the tank but I have ‘lost’ Scampo several times!
Scampo has already shed a skin, and his colour gradually returned over the course of a few days.
