Hi I have a 60L biorb tank, its already an established tank but it's just empty at the moment. It contains 2 tall silk plants and a couple ornaments to hide in. I know that biorb tanks aren't ideal for keeping most fish but I dont have the money to buy another tank at the moment so it will just have to make do for the time being.
I'm a bit unsure on what kind of fish would be good for a tank of this size and shape as it's quite unusual and isnt ideal for a lot of fish.
I was currently thinking of getting 3/4 variable platies (1 Male 2/3 female) but just wanted to know if anyone would reccomend anything else instead or if this seems like a reasonable amount of fish for the tank.
You're correct in that almost all fishes' requirements are for something with a 'footprint' (and thus swimming length) of a certain size, the minimum for some small fish (e.g. small tetra species) being 60x30cm due in part to such fishes' requirements of being kept in shoals. [ You'll see here that the same minimum footprint requirement applies to platies https://www.fishkeeping.co.uk/modules/ ... sheet.php?caresheetID=202 - and note that, even if you did have a suitable tank size, even one female in the presence of a male would result in you soon being over-run with fish as they can store fish sperm and continue to reproduce for 6 months post-contact with the male.]
Thank you for the perfect answer! If I was to get a fighting fish for the 60l biorb would if be best kept alone, ie. No other fish in the tank PERIOD, or are there any other fish that would suit the tank alongside it or instead. Just seems like a large tank for one fish although if this is what you reccomend then I would happily give up the tank for just the one fish. Also the tank is currently filtered with the stock biorb filter but it doesnt have a heater so would the fish need a heater or is it okay at room temperature? (18-22 degrees usually)
A quick internet search for "betta fish food" brings up a list of dried foods via Amazon from the key brands, formulated specifically for bettas. As well as the live/frozen food referred to in the above links and which are a key part of their diet, for the dried foods, choose pellets over flakes, and opt for sinking or semi-sinking over floating pellets.
