I have had Tiger Barbs live for 3 years in my tanks.

Thanks for that info. Was this a community tank? If so, what other fish did you keep them with and were they good companions?

The lifespan ? I can not answer but other semi-aggresive fish would be a possibility. Red tail or Rainbow sharks I think might be an option. Rosy barbs are very beautfully colored. The only problem is an adult tiger barb can grow to 3" and that will be a tight fit for very active fish in a 20 gal. You will have to trade them out when they become that size. Or get a bigger size tank. I have seen and heard of them being kept with African Cichlids but IMO I wouldn't because of the desired pH difference.

I have a 30 gallons tank and currenly filled with 10 Tiger Barbs, 6 Platies, 2 Dwarf Gouramis, and 2 Striped Raphael catfishes. They all are happily swimming together.

i have a tiger barbs in my tank and one of them got a red spot that looked like a zit on its head that kept his mouth from closing...its going down now...but can anyone tell me what could have caused that?

I had this happen also, I tested the water and I actually had signs of ammonia in it. I did a full tank clean and scrub down and it went away.

I have a tiger barb in my tank and he’s 8 years old. Still playful.
