I have a 180L (50 gallon) tank, I've heard too many male sparkling gourami can become aggressive? I'm trying to plant my tank out more and waiting on my twisted Val to gain height, but generally sticking to 3 kinds of java fern with spider wood driftwood. I really want to try going for a nano style (small fish look) rather that a full blown nzno aqua style tank.
How many could I get for my tank.
Current load is
9 Marble hatchet fish
30 chili rasboras , 10 spotted dwarf rasbora
20 emerald dwarf rasbora
8 panda corydoras, 6 Venezuela Corydoras
4 otos, 1 hillstream loach
6 gertrudaes
