Tinfoil barb tank mates
Grows to 35 cm and needs a school. Juvenile 'showpiece' fish sold at 5 cm; outgrows 90% of buyers' setups within a year.
Common mistakeBuying three cute tinfoil barbs for a 100L planted community is the textbook outgrow-and-strip story. Adults push past 30 cm, need a huge footprint, and treat soft plants as salad. This is a public-aquarium-scale school fish, not a silver tetra for a living-room kit.
