    My cardinals are behaving a little different from yours. They are swimming freely around the tank. However, whenever someone approcahes the tank, they will go hide behind the driftwood or at the back of the tank. Of course, they will come towards me during feeding time.

    Hi all of you checking on characin ages...

    this is Heiko Bleher collecting tetras (and all other fishes) for several decades now and I wanted to tell you:

    1. Cardinal tetra live in nature normally never more than one year, but in aquaria, well kept, 10 years is not rare. As a matter of a fact, my dear friend who unfortunately past away last year, Jacques Gery (see www.aquapress-bleher.com under Special Events), and who has described many characoids including the Paracheirodon simulans (and a new neon I found last year, to be published soon) had in one aquarium a few Cardinal tetras for almost 12 year, without a filter or air stone in it...

    2. One must naturally distinguish as there are more than 1600 different characoids in America and Africa, and some are very predatory fishes. But I would say that an age of 2-3 year is normal for most, and well kept, most of the will live much longer in aquaria.

    3. And remember: in aquaria all fishes if kept well (and definately the best is to keep them according to their habitat and nature, which by fat is best - have alook at my Biotopes, that is the way fishes should be kept - in their own communities within their authentic habitat) live much longer than in nature. Ie Hemigrammus bleheri (the brilliant rummy nose) and Cardinals, both in larger groups, make a perfect environment, they live together...

    All the best

    Heiko
    Best regards,
    Heiko Bleher

    i bought 16 neon tetras since march and only 13 survived to this date but all have grown bigger since.. hoping to find a good source for cardinals... much tougher than neons i think but rare in our LFS...

    Re: Lifespan of tetras in your tank?

    most of my cardinals and black neons survived 2.5 years+. now dying 1 by one when i mixed with 2 female guppies. i think due to over crowding as 2 female guppies were preggy and did not stop giving birth until the next generation was old enogh to continue breeding process. so from 2 guppies i have like 30+ guppies. and from around 40 tetras, i now have only 15.

    Most of the South American Characins I prefer to keep have lived between three and five years for me.
    I have had an Nannostomus eques live close to seven years but it outlasted it's mates by about three years.
    Old fish breeder. SA Dwarf Cichlids, Hypancistrus sp L260, L333 and Peckoltia L134 breeder. Also Sturisoma, Dwarf Corydoras spp, wild Discus and Killiefish. Like breeding Characins and wild Betta spp too.

    my neons seem to be quite aggressive, think they will kill each other before they reach old age... some have bite marks but they are a pretty active bunch

    Re: Lifespan of tetras in your tank?

    My water pump was giving off a humming sound and I peeped into the hidden chamber to look. There in that cylindrical box was a tiny neon tetra that I though was eaten by a gourami and I had the culprit removed. (regret! How did it get there?!)

    It survived 6 weeks without food and in strong current within a confined space while its cousins are already twice its size. So much for the remarkable resilience of tetra.

    I disconnected my Ehiem for cleaning yesterday and found two shrimps very much alive..... but due to my fat fingers, I killed them while trying to get them back into the tank

    Re: Lifespan of tetras in your tank?

    Hi, I've got my cardinals for 2 months but their colours are still dull from the time I got them.

    Any suggestion to improve their colours this? I'm feeding them pellets and occasionally brine shimps.

    Whats the pH and TDS of your tank water? Cardinal tetras prefer lower pH and lower TDS water (ie. soft acidic water), so that may affect their overall condition and colors.

    Maybe you can try feeding them pellet food with color enhancing ingredients, can try brands like New Life Spectrum Small Fish Formula, it works well for my fishes.
