Hey, I have a 29 gallon tank currently stocked with 9 rummynose tetras, 1 platy, cherry shrimp,5 nerite snails, and some pond snail infestation. My ph is 8 and the temp is 78 F, and I have 2 amazon swords, 3 narrow leaf java Ferns, 1 regular java fern, and some Italian val. I’d maybe like to have another schoal of fish that would contrast with the Rummynose. I don’t really want a centerpiece fish, but i’d consider whatever ideas you guys have. My filtration is a 20-40 aqua-tech filter( will hopefully be replacing soon with a sechem tidal 55) and a small sponge filter.
