    Really not suitable for fish. You could, however, put some cherry shrimp or similar in there and it'd be a nice little piece of nature with some plants etc. Whole heartedly recommend checking out UKAPS forums for planted tank info and help.

    Yeah it's even too small for a betta. Few cherries would be OK at most

    Be running to the toilet every few minutes listening to that running water 😁

    It still amazes me people put goldfish in tiny bowls etc. You really need at least 20 GALLONS per goldfish! They are incredibly messy fish and you need that much water to help dilute down the waste in-between water changes etc. 20 gallons is kind of extreme and you can get away with less, especially when small, but you need to keep on top of water changes and the water quality to give them a good quality of life.

    Not a tank suitable for fish. Looking at the Argos reviews people are putting goldfish in these.

    3 or 4 guppies and 1 small ancistrus to eat the algae will be fine in there, just change half the water every week.
