I haven't posted here in a while, but I need some advice, so here's the deal. I just inherited a 20 gallon community tank from my brother, who was getting bored of it. pH is 7.5, and the temp is usually at ~84 because the blasted heater is broken and can't be adjusted anymore. It is currently housing 5 Gold barbs (
Puntius semifasciolatus) and a Siamese algae eater (probably
Crossocheilus siamensis). I was wondering what types of tankmates would be suitable for this setup. What does everyone think?
