I have a 145 liter freshwater aquarium that hosts 15 wild caught cardinal tetras among other fish like ram cichlids and catfish.

I have had this aquarium since late december of 2019 but I only got it set up and running during early january and back then it was just 10 tetras and 4 corydoras duplicareus catfish that kickstarted the nitrogen cycle for my undergravel filter.

I recently got the idea of feeding my fish other things besides the tetramin fishflakes and the frozen mosquito larvae because I am gonna try feeding them tiny pieces of frozen spinach and eventually daphnia.

I have read how to breed daphnia but the only problem is that wherever I look I can not find any info on how to find infusoria starter culture that does not involve buying it or asking for others that have it.

I am interested in making my south american blackwater aquarium as authentic as possible without going too far with it which is why I am gonna try feeding them things like fruits , veggies, and crustaceans like daphnia .

The choice I think is buying it or collecting it yourself. The small bags of daphnia that you can get in Fish shops in the UK cost about £1.50.

Cardinal tetras don't eat spinach but you can add green water to their tank.

Unless you live near a lake or pond, it's easier to buy a small bag of live daphnia and use that as a starter culture.

The following link has information on how to make green water and infusoria cultures. Daphnia can be kept in and fed on both of these.

Well luckily I live right next to a decent sized lake in the countryside so that should not be a problem.
