Threadfin paradise fish

Bare and the sand only covers half the bottom, they're open water fish that dont appreciate obstacles in the tank as it would only mess with their non stop activit and since they are extreemly sensative to nitrates it is easier to keep an almost bare bottom clean.
 
I was just wondering what their natural environment looked like and expected these guys to be nocturnal (but I might of course be wrong) - which is tricky to simulate in a tank with nowhere to hide from daylight :dunno:
 
I dont think the fish has a prefference bewteen night or day, normally if fish are nocturnal they will attempt to hide behind anything they can even if the only thing in the tank is a filter but this fish just swims non stop night and day. The tank isnt usually as bright as it is in the pictures, i have a black plastic lid which shades half the tank and cuts down on the brightness but i had to remove it to get clear photos.
 
CFC..having started out with FW and now doing some marine, you can help teach us some stuff. How are you going to bring up your salinity for this fish? Do you use aquarium salt or a marine salt? Are you using a refractometer or hydrometer to check the s.g? Do you premix the salt with FW and do a slow drip in? How slowly do you raise your s.g for this animal? Once you reach brackish parameters, will you need to 'topoff' like us? Thanks for your replies.

Great fish. Since starting here, I've learned alot from your fishkeeping.SH
 
PS...what is your 'fish census' now and tank number? LOL. Just curious. SH
 
Wowzers! Those whiskers are just so cool. And my lord there are so many lol..and here I was thinking my UDC had a face full :lol:.

I found a few good shots of these fish...for anyone interested..since it seems they move so fast it's hard to get a picture (thus the 300 deletions :crazy: ..that gets annoying doesn't it...trying to take a pic and the darn fish won't cooperate lol).

Pictures of a grown, wild caught one..yikes!!! But I don't think this is the exact same kind though..but similar

Here's something I found interesting though...

Interest to fisheries: Reportedly some species are of commercial value but in Sri Lanka they are not abundant; some are of interest in the aquarium fish trade, especially the juveniles which form very dense colourful aggregations; many with very painful sting.

:eek: Jeeze..Don't make it MAD!
 
Ah, finally posted up about it :) Nice, but why not stick with something that has been kept alive longer than a period of nanoseconds (or thereabouts)? Like.... a nice betta :dunno:

*pouts* I want a fish so rare that God hasn't even seen it :( -_-
 
what size tank is that thing in? too many whiskers for me... but other wise a great fish! i love fish that never stop moving! :clap:

what size tank is that thing in? too many whiskers for me... but other wise a great fish! i love fish that never stop moving

30x12x15", around 25g
 
Blimey, that's some find! Gotta love those tentacles.
Did the store know what they had? If they had it in with angels It sounds like they had no idea!

How much was it?
 
Bargain price of £60, the store had some idea of what it was but didnt give a damn how it was kept, not only was the tank full of angels it was also only about 12x12x12" so the poor little guy looked like he was break dancing on his head as he swam around and around. I think they just order in anything different they see on the wholesalers list as a lure to get people in the shop, they might not sell the oddball fish but people hear that they have unusual fish in, visit the store for a look and end up buying something just for the sake of it. A couple of weeks ago they had Mahseer in stock! (and yes i was tempted :lol: )
 
Wow, amazing find!!! If your shop can get one in, perhaps you could see if they can special order another :shifty:

To bring the salinity up i will simply just mix a brackish solution in a 10 litre bucket to around 1.001 then doing daily 10 litre water changes exchanging the water in the tank for the brackish solution in the bucket. When the SG in the tank measures 1.001 on a hydrometer (should take around a week) i will increase the strength of the replacement water to 1.002 and carry on as before until the tank water matches this. I will carry on this pattern until i reach around 1.005 where i may stop until the fish has reached near adult size depending on how the fish is reacting to the increased salinity, juvinile brackish fish often stay closer to freshwater than adults. Refractometers arent needed for brackish tanks as the stability of the SG isnt as crucial.
Brackish water does need topping off with pure R/O just like marine does, just not to the same extent as it doesnt evaporate as quickly due to the lower salinities..
 
Interesting...thanks CFC. Weekly water changes must keep you busy. WTG. SH
