How long in a standard 75 g?

[santoury]

What is a YOY annectens?

I didn't imply that being in a small tank would lead to health issues (since you brought up HITH, excellent patterning) It's just that I like to have my fish be able to turn around without folding itself up.
A 20 inches is a very small 4 year old, BTW - Mine have all been reaching 16 to 18 inches in 1 to 1 1/2 years.

I'm not sure what you meant by genetics - they are all wc...

genetics plays a role even in the wild...do you think it's just in captivity??? there are big fish and small fish in the wild, not all of them reach wild max (most do not)...trust me, i work with thousands of fishes from the wild and this is blatantly obvious, even if one doesn't understand basic genetics.

if genetics didn't play a role in wild caught animals, they would all be the same size and condition (condition has to do with health of the fish in various parameters).

YOY = young of the year --

Of course, genetics plays a part everywhere, but there is a known "adult size" for each species - and 3' is the typical adult size for annectens (As opposed to say 4' or what have you, for dolloi, etc)
Quite simply, this is a fish that is known to reach, and often does, reach 3' so the owners should plan accordingly. No use in "hoping" you'll get lucky with a "runt" such as your 20 incher. (And yes, I do mean you are lucky)
That's all I'm saying - is that each responsible owner should plan on the fish growing relatively close to the adult size known.

the wild max for annectens is 100cm...we'll further debate max sizes vs captive sizes later as i don't have time now, and definitely don't have time to give you a basic genetics lesson OR debate "responsible fish keeping" with you--

PS - this is, believe it or not, like having to plan for a 14' arapaima or 11' alligator gar...but the big fish debates can also wait, and are somewhat of a digression. show me a captive Florida gar that is 54" that has been raised by a private fish keeper since YOY status as well while you are at it

P.annectens may reach 3' in captivity, but that doesn't mean it can't be healthily maintained in a 75g for some time prior to that--

of course a 2 inch annectens would be perfect in a 10 gallon tank. I'm not stupid. and for your information, 100 cm is.... lo and behold, 3 feet.
You're lucky you have a little 20 incher so you don't have to lose sleep over being a responsible fish keeper, as I do, having several at the 3 feet mark. I hear people on here bemoan every time they hear of a 3 foot fish in a 125 (Indeed, people say a single big male dovii or something would be kind of cramped in a 75) I don't think that says very much, on your part, for saying it's okay to keep a 3 foot lungfish in a 2 foot wide tank.

I keep 3 foot lungfish, and I know what makes them tick, so I'm done here. Don't bother responding. I won't waste my time any further.

For a fish, ANY fish, known to reach 3 feet, I would never recommend a 75, unless if it were a youngster.

ok with the hopes of getting back on track with the subject at hand, i am saying that it's very possible to keep an annectens lungfish in a 75g tank for a while. obviously this is meant for a younger fish, not an adult. you have to keep in mind that the tank size must be sometimes tailored to the fish, and everyone knows that using a step-wise tank size method works well for many predatory fishes. i've kept plenty of fishes (many of which can clear 3' in their wild max) in smaller tanks until they grew to a size where a larger tank was appropriate.

so to the author of this thread, go for it...get a small annectens lungfish, keep him by himself in your 75g. make sure the tank is well-filtered (i would recommend at least one AC 500 power filter, but two would be better), and do regular water changes, i'd recommend 50% per week, but more frequently if you can afford to do so). temp around 78-82F will do, but try to keep things consistent, and feed meaty foods (frequency will depend on the size fish you get, and those questions can be answered later once you get said fish).
regardless, you'll be able to keep the fish just fine in that tank/setup for at least a year, probably longer. you can then make your plans for the larger tank, but as with any large-growing predatory fish, it's best to have that larger tank on hand if possible.

good luck, and let us know if you have further questions!--

Couldn't have said it better myself - you won't be disappointed with the fish - that's for sure - just have a big tank ready, like he said.

Annectens DO reach 3 feet rather easily in the aquarium. I have seen about four at that size in this past year alone - two of which are mine. a 2 foot wide tank will NOT be sufficient.

wow 3 ft already they did some massive growing. How did you manage to do that? just under half a year ago your biggest was 2 ft and the other ones 1,5 feet. that is 1 and 1,5 feet in under 6 months. fck, what is your sectret.
did all 37 of your lungfish have this growth rate? you must have had some issues with the housing. You started out with your lungs in 2,5 gallon tanks and your biggest tank was 100g long if i'm correct, how is the greenhouse comming on?
I would like to see how you keep your monsters.
