Since your guys are still small might be a good time to find some dithers or mid upper lvl fish. Larger barbs like filamented, roseline, eyelash, spanner t. I had a hard time when trying to find a sutable dither that was a price point I wasnt worried about. I had some filimented barbs but they wasted all my plants. I've got congos now but pretty sure if they go in they'll be eaten. I did put 2 geos in but then you are mixing continents. I guess the barbs are too lol.
Tank looks great! So jealous of you guys that can get the garnet. I can get it if I order a pallet....lol. I dont need 2000lbs of garnet.
