I keep my betta on his own in a 20litre (4.3gallon) tank, he's a very happy chappy.
However when feeding him I'm always in need of cleaning his tank due to the scrap bits of food on the floor, & with it being sand its a nightmare to filter all the waste & I usually remove him when doing so.
Therefore I'm wondering to get something that would live on the ground & help me keep it tidy?
Do u think this is a good idea, keeping in mind I don't want to upset betta with an uninvited friend, & do u have any suggestions as to what I could get if this is a good idea, keeping in mind the size of the tank.
Many thanks as always for your advice.
