my sister was recently over and asked if she could have my old 20g long for christmas. delighted that she was interested in fish i said of course. i ended up getting a HOB on black friday for like $5 and i have some old sand i was gonna give her and a small flower pot. any recommendations for a beginner? im not sure how dedicated she will be towards it but ill push her in the right direction. i was thinking cons but then she might have to deal with a bunch of fry. then i was thinking apistos but im not sure if she would be a good enough keeper for them. any suggestions?
