My Mystery Fish

[spacebass]

Thank You.,

some kind of speckled molly?

[cometcattle]

Almost looks like a Koi....

 

[Jer-]

I would also say some kind of mollies becos of their obvious up-turned mouth and the blocky shape of it.

 

[JackDemp528]

Yeah it looks like mollies to me. the mouth gives it away. Kois have down turned mouths with barbels.

 

[Jen]

I would say a molly or platty of some sort.

 

[Durbkat]

They look to big to be a molly or platy unless he has blown up their size so you can see them better but if he didn't do anything to it, it looks like some kind of koi or goldfish.

I take it you own these fish? Including the ones in the other thread? You should know what kind of fish they are and what requirements they have. Research in to a fish before you buy is a must and will ensure you give your fish the best home possible.

Hi I posted the fish on this forum because the others do not have a 'browse computer' feature but require the entering of an URL which is beyond me.

On the other thread (on which I referred the readers to this page) I stated that they are about 1.5" long and should have done so on this page. I am sorry, i also have removed them from the tank because they, when together, nip at my goldfishes fins and rear body ( I know Goldfish should be in cold water but there isn't any in Thailand!)

When separated into individuals they become very insecure flitting up and down the tank wall ignoring the other fish, but when put together they start worrying the other fish again.

I will be taking them back to the store because of their aggressive character.

Yes i do currently own them but I will shortly be returning them to the store as above, I am in Thailand and cannot talk to anyone in the stores , and I am not sure that the assistants in the store have quite the same attitude towards fish as we westerners anyway, I watch my fish most of the time and if they start bickering or I see any untoward situation I try and resolve it.

Plus I am confronted with the strange stituation that I have yet to hear a sensible answer to (sorry to go on) that I have goldfish in 28' c. water as every other goldfish in Thailand and no doubt the tropics in general is to be found, and they are very popular being 'lucky money fish', which does not concur with the accepted view on goldfish treatment in the 'civilised' world (let alone tropical fish).

You shouldn't rely on your petshop for information on fish anyway. Use books or the internet. Find what the scientific name is of any fish you see (or a common name if you can't get the scientific one) and would like to keep but don't buy it. Go to www.google.com and ask on these forums for info on it. Then you'll know whether it's suitable or not.

As for the goldfish. Goldfish are extremely hardy fish and can adapt to all sorts of water conditions. However, just because a fish survives, it does not mean it is being kept in ideal conditions. Having said that, a lot of fancy goldfish are bred in warmer water and do fine, if not better, in the lower tropical temps. However, with all goldfish (but especialy common types), warmer temperatures cause an increase in metabolic rate which is unnatural for a coldwater species. The result is a shorter lifespan, faster growth, more need for food and much higher waste production. As goldfish are already very high waste producers and as higher temperatures also allow less oxygen to be held in the water, keeping them at a higher temperature makes it necessary to change their water more often or, alternatively, keep them in even larger tanks. You should be aware that the general rule for goldfish stocking is 20 gallons for the first fish + 10 gallons for each additional fish. If you are keeping commons or larger fancy varieties (though all - even bubble-eyes - will get to 7" or so) you should try to provide at least 20 gallons per fish - particularly if you consider the higher temps.

As for keeping them with tropicals. Considering the size and amount of waste of goldfish, the health of more sensitive tropicals is bound to be compromised. Also, goldfish wont do well in the higher range of tropical temps that some tropicals require. Goldfish also tend to have a natural curiosity or tendency towards swallowing things which can lead to serious issues with smaller tropicals and, especialy, fish of around 3" such as cories which don't quite fit in the goldfish' mouth but fit well enough for both cory and goldfish to end up dead. Then also consider that many fancy goldfish types are especialy prone to certain diseases or are very slow. These find it difficult to compete for food with the faster tropicals and their tendency towards succumbing to disease (particularly when not kept at the ideal temp., which encourages bacterial infections) puts all their tankmates at risk.

Also, as you've seen with the mollies pictured above, many tropicals find goldfish easy targets for nipping or harassing while for other tropicals the opposite is true. You probably are also aware that goldfish often damage or uproot plants - plants are generaly a major component of a tropical community tank.

So there's a good number of reasons for keeping goldfish and tropicals seperate...

Thank you for this great information, and yes I do have to put a pot of plants in the tank every week because they are blitzed, the question now is if I were to return goldfish to the store because I have too many are they likely to end up mollycoddled in a 20 gallon + 10 gallon tank or in a smaller less cared for tank than even mine!!! TiT!

I have added an air stone which seems pretty necessary from what you say and I change about 1/3rd of the water every week now. quite a lot of waste seems to float around the edge which I hook out most of the time, I am currently trying to find a vacuum so I can clean the bottom.

I plan to buy a huge tank when my sharks get a bit bigger!!! and funds permit.

As far as food goes so far i feed only two sizes of 'Sukara' fish pellets which says it is 100% complete advice on supplements to this would be appreciated that would not destroy the water too much. All my goldfish hoover this up and it is the smaller fish I worry about as even the small pellets seem too big for them, are they getting some food when they toy with these pellets?

I like to leave water overnight before adding it to tank, I also add conditioning liquid but when using conditioning liquid how long is it a good idea to let the water stand minimum?

Looks like I am going to end up with a condo full of 125gallon fish tanks!!!
