Little update as it’s been a while since you guys have heard from my tank! After losing one adult Harlequin Rasbora, the other 5 adults and 3 babies seem to have adapted well. They’re all still swimming happily together in the middle of the tank.
Despite having only 4 Cardinal Tetras (which have amazing colouring!), they seem to be quite confident and are very happy to be seen in all area of the tank.
My plants are doing ok but I’ve had to take one or two out and have now been replaced with others so I stand at 4 types of plants alongside a big hunk of floating water sprite which is doing amazingly. It’s put down some really quite long roots and has quite a lot and the Cardinals in particular (and the baby Harlequins) enjoy swimming through the roots after their feeding time. I only have one water sprite shoot in there as it’s quite big and if I had more, it limits the amount of light the plants at the bottom get.
I’m still struggling with snails (the Assassin snails did nothing to help before unfortunately dying) but they’re not causing a problem so far.
Two days ago I changed out the other half of the filter media as suggested a while back so it’s now all sponge. I also gave the used filter media to my sister in a hopes it will give her next fish a better chance of surviving since she’s running her filter with that for a time before getting the fish. I realise it might just kill the bacteria to go into colder water but worth a try I suppose.
Once the 6 weeks is over, I plan to get another 4 Cardinals to boost their numbers so will have equal numbers of Cardinals and Harlequins, having abandoned a hope of a suitable feature fish.
There is a chance we will be moving house soon however and there may be a possibility of a second tank for a Betta or if not, I hope to get one once I have set up residence in Newmarket alongside my existing tank.
Hope you enjoy the update, let me know if you have any questions or if anything I said could be improved.
