Inbred is generally not used to describe F1. It is used on fish that have been bred back to each other to the point of increasing illness and defect as well as overall poor health. By that point it will be next to impossible to determine how many generations from wild they are. A well bred tank raised neon is going to be hardier but massively inbred animals of any type are almost always weaker with genetic problems. If new blood is not introduced without a very strict culling practice then the fish are going to go downhill. Inbreeding is only good when you are breeding very superior animals to each other and only for a generation or 2. I would definitely go for a wild caught neon than the tank bred ones I see around here.

"there is a reason why most places do not obtain wild caught neons, as they are incredibly vulnerable to pH shock, tetra shock stress, and ich, among other. Most imports do not make it out of the bag."

IME, cardinals included. In our store, it's the exact opposite; wild caught cards directly transported do poorly, whereas tank bred and tank raised specimens seem to have, at most, 4-5 casualties. We rarely lose neons.

All of the cardinals we get at work are wild-caught (sometimes we get some really awesome rare contaminants with them), and they are always hardier than the farm-bred neons we get in.

Usually we don't lose a single cardinal from most shipments, whereas with the neons it's not uncommon to lose up to 10 of them.

Are you referring to all wild caught fish, cardinals included?


My Scapes

In what way do you mean?

Are you referring to cardinals as well?

All fish need good water, with regular water changes & good food & i also think that Cardinals are harder then Neons.

Inbred can be used to describe any generation following wild. Poor health does not generally occur as a result of “inbreeding”. Any parasitical immunities they once had will be retained. Besides, a good aquarist does not generally have many outbreaks of disease, so health should not be a great issue. If anything, they are more able to adapt to conditions within four walled environments. Of the millions of neons out there, it is hard to believe that inbreeding on a massive scale occurs. Furthermore, there is a reason why most places do not obtain wild caught neons, as they are incredibly vulnerable to pH shock, tetra shock stress, and ich, among other. Most imports do not make it out of the bag.

trust me that water was not good, but they seem to do just fine. it is odd. i heard that they need good conditions,but i wasn't giving them that and they are survieing. i changed the water last night so it should be good.

You just solved your own problem. If you know that the water quality isn't good, then don't be surprised when fish die, simple as that.

i was told that cardinals are harder to keep, but in my school of 17 there are neons that gone missing.they may have died or been eatten. so what is going on.

"inbred"...

If by inbred you mean they'll feed on prepared foods without a second thought, are more comfortable with given water parameters (as opposed to the ridiculously low pHs they're normally found in), grow larger (or are harvested at a larger and more consistent size), and are parasite free, then yes, they are inbred. Cultured fish (F1+, human raised, etc.) are more sought after than wild caught specimens.

Btw, cardinals can get NTD too--in fact, most fish can get it. The commonly held belief that NTD is unobtainable by cardinals is completely false. It is unknown what triggers NTD, but I can tell you from firsthand experience, if kept in good conditions, neons are unlikely to obtain this parasite, as I've experienced no cases in the many fish I've dealt with (I, on the other hand, had two cardinals develop NTD).

Yup, cardinals are hardier. They grow a little larger as far as I've seen, are somewhat more tolerant of dirty water, and are far less inbred (if at all). The major thing though, is that cardinal tetras are much less likely than neons to carry the dreaded Neon Tetra Disease, a pretty much unstoppable sickness. I've seen several bouts of this in tanks as work, and it is not pretty. In fact, I noticed a neon today that had it.

My cardinal tetras have proven themselves to be tough, they're pretty happy in my tank's pH of 7.8.

I believe that cardinals can be considered hardier than the farm raised neons, because they are inbred too much. Wild caught neons can be another matter. They are hardier than their farm raised cousins.

I found cardinals are hardier than neons. I've had a cardinal in my 25g for a few years now, and it isn't really kept in the best water. (I spend too much time looking after my 115g instead )

umm. about a month give or take.

How long have you had the cardinals.

That answer is not that easy. Cardinals once established are hardier than neons. But you need to have very good water quality for cardinals.

20% water change weekly minimum.
Established tank (IMO at least 6 months old)
