Greetings to you all on this fine forum, I have been keeping Clown loach for 2 years maybe more I do not know exactly but that is inconsequential as the joy of keeping these wonderful loach is the same today as it was when I first discovered there appeal in my early days.

Like most I have spent an age reading about the species as well as observing them, doing my up most to provide them with the best environment and food as possible for there good health and happiness.

However I have to admit some frustration in my knowledge of this fine species, so I thought I would venture some questions to you fine people to see if there is something new or something I have missed to plug the gaps.

Sexing the species: As I understand sexing the species is almost impossible on living Clowns and that we can only verify this when they reach there adult size and the females become more bulkier a wider width looking from above? There is a theory that you can at adult age identify a male from a female from the shape of there tail fin and that the males fin tips point in a little resembling a subtle claw like shape? Is there any fact to this? Are there any other ways that have been proven over the years other than doing an autopsy on a deceased fish?

I have mentioned about when a Clown loach reaches an adult age, when is this? I am aware that they can live to 20 plus years if kept in ideal conditions. So if we consider keeping a group of Clown loach in minimum conditions of a 6X2X2 tank with good water conditions plenty of flow subdued lighting with a good and varying diet. How old is a Clown at 2 inches in length or 6inches in length etc etc? I do realise Clowns are not going to grow uniformly they are going to vary in the speed they grow, but would any one like to venture there thoughts on this? is there a rule of thumb as the saying goes? I have read one article saying the 7 to 8 inch size I have also read 7 to 8 years of age is the point of maturity one can get very confused by it all and being an Engineer by trade I am guilty of liking exact facts and figures which I know I will never get when It comes to Clown loach but hey we can only try!

Breeding Clown loach? has it really been done in captivity I like most have read one or two brief accounts of breeding Clown loach in captivity is there anything to this? I am not asking how because I have absolutely no inclination of achieving what appears to be the Holy grail of Keeping Clown loach, well not at the moment anyway.

The Clowns we bye in our local fish shop's are they from the wild or are they from farms? I read the majority are from the wild, but do these farms I here about exist? This leads back to the whole age and size question in that: If the average juvenile Clown we see in the shop for sale is 1.5 to 2 inches long how old is it when it is caught how long do these poor little fellows have to endure what I can imagine is a retched trip to get to the shop? Or if they come from a farm are they being compromised due to the steroids and drugs I have read that are used to help bread them? Will the farmed fish over a period of decades de-gradate like some other species of tropical fish through in breading? Again how old are these fish when they are in the shops at the size of 1.5 to 2 inches and is there a difference in size between a farm fish and a wild fish?

I frequent many Local fish shops and never fail to stop and study every Clown loach they have as I have a great interest in what would be considered odd marked Clown Loach, just the other day I asked my wife to drag me out of one LFS before I purchased a 1 inch double dot on the belly clown Loach with one stripe! Fortunately for me and according to a couple of shops round my way odd marked loach are quiet unpopular so if he or she? is still there next time then maybe...lol.... so does the markings differ more on farmed or wild species?

Well I do hope some of you venture what you have learnt or experienced and please be assured I am not being lazy I have searched and searched on the web and read stuff from the tenth and twenty first pages as well as the first of Googles results I guess I just cannot get enough information on these magnificent Loaches but I am sure I have missed some of the good bits of information as you can probably work out from my ramblings above, the length of this post I must apologies for.

No one? :crazy:

Nothing? :unsure:

Well its something to celebrate my first post without a single response :lol:

Actually this is just a shameful excuse for a bump :nod:

This is what happens when you pack together more than a couple questions.

OK... some answers: it is likely that one can sex them with the side view too, the females develop more girth. The more dominant fish is also likely to be female (true for most loaches). To the best of my knowledge shape of fins is just a guess someone made a few years ago, not proven. Yes, autopsy seems to be the only proof.

Rate of growth: depends on many factors.

Adult size: clowns of 5"-7" were bred.

Lifespan: in good conditions, 40 years is also possible, maybe more.

Breeding: yes, this was done. There was a detailed account of this; this was done by a fishkeeper in Ivanovo, Russia, about 3 years ago. There is also an account of US breeding which is likely untrue.

Most clowns are farmed, and juveniles are sold. Wild caught are rare, and there are export restrictions on large clowns.

Odd-marked clowns are fun... here is one of mine:

(the photo is from Feb of 2006.... the fish grew from 2" to perhaps 6" since, and appears to be a female...very deep.)
 
Nice one Mikev :good:

More than a couple of questions :lol: , I did add quite a lot of information to my post that I was aware of so I did not get the basics repeated to me over and over again.

I have found since I got into the species and started consuming the information available, it has never changed there is no progression and this I find is quite frustrating.

I was reading an interesting article about the first company De Recherche (French) in partnership with the Indonesian Ministry of Marine Affairs to bread Clown's in captivity, I was surprised by your statement wild Clown loach are rare in LFS now a days considering the complexity's of breeding these fish, but I guess it is the sign of the times but that can be a good thing if it allows the species to thrive in the wild with out interference and reduces the number that have to endure the terrible and arduous transportation to there markets country. Let us hope the species does not weaken like some others have through constant captive breading.

Thanks for sharing the picture of your odd marked Clown he/she is fantastic that is a well formed spot I have one with a spot but as he/she is growing the spot is starting to move closer to the back stripe.

You should not be. There is a world of difference between captive breeding in an aquarium and captive breeding in a pond (or netted off part of a river) in the country the fish originates from. The second type of captive breeding is nearly natural.
 
Of course I am aware of the vast differences between breeding a fish in a personal aquarium and a commercial set up my apologies I did not make that clear.

Sorry I am getting a little confused when I think of fish farms I think of some were in this country were they are farmed in big open air tanks with the use of steroids and the owners are nothing but profit orientated.

Are you saying they are still farmed in there natural habitat in the Malay peninsula, Borneo, Sumatra area in the main also they come from Kalimantan?

I can see how setting of a bit of river would make an excellent place to breed them.

May I ask your sources of information and if you could share any links you have as I kind of collect information on the species?

Thanks Two I am also a member and have a similar post with them but thanks for mentioning it :good:

I am not a member there but have relied on the site for loach info for years. Here is a poor pic of some of my clowns (that SAE is about 5 inches).
