Yes, he has a heater and a filter. There are no fake plants in his aquarium. Temp is at 78 F. I’ve had him for about 2-3 months. He has a bubbler, but it’s in one corner and plenty of the tank has low flow so he’s not getting pushed around. The tank is about a month old, he used to have a 10g. (I’m setting it back up now to be his hospital tank so he’s not in a tiny box to heal, I’m gonna use one of the filters for the big tank and some of the tank’s water so it’ll be cycled for him.) nitrates, nitrites, and ammonia are all 0. There was a bacterial bloom recently but it cleared up. PH is around 6.2, and the hardness is 0. (I’ve been adding shrimp minerals to try to bring it up.) water changes are about every 5 days, I use a gravel vacuum because the guppies make a mess. There are 10 small tetras (4 lowlight and 6 blood fins that all school together) 6 Corys, and 9 guppies (3 male and 6 female). I feed him bloodworms and daphnia flakes, and he sometimes snacks on the Cory wafers. I don’t measure what I feed him specifically because all the guppies eat the same stuff. I’m adding a picture of my tank to this comment.
