I have a single bolivian ram in a 29 gallon tank - he had to be separated from my 55 gal as he was pretty aggressive with the other rams (though never had any issue with the kuhli loaches or harlequin rasboras in there). I tried him in another 29 gallon with panda corys but he was mean to them, bumping them and generally earning his namesake, "Dink." He was added to the cory tank - maybe they were too oblivious and sharing too much of "his" territory for his liking. Strangely enough - and this could be because I added him to the Dwarf Gourami's tank - he spent two days being chased and bullied by the DG which I ended up moving to the cory tank because Dink was pretty stressed out. So right now he is in a 29 all by himself. Temp is 23.5 C or around 74-75 F. Planted with sand substrate and some driftwood and river stone. Lots of floating plants. He's actually a bit shy in there by himself so I was thinking of dither fish for him. I'm limited by what is available so I was thinking: 1. Endlers (prefer all males but is this a good way to keep them?) @endlercollector ? 2. Platys 3. Neon tetras 4. Pristella (X-ray tetras) What would you pick and how many would you put in? My filtration is a Seachem Tidal 55 and a sponge filter rated for a 60 gallon.
