Help with Goonch Identification / Heat resistance?

  • We are currently upgrading MFK. thanks! -neo
My tank is about 135g and the return pump is rated at 1500gph but realistically it's probably pushing about 1200-1300gph. I also have a large koralia on the floor that's rated about 2000gph just for the goonches. They like to hang out right in front of it majority of the day but a few times a day they'll take a rest and hang out in the low flow zones. I've had them in a tank when there was just constant flow everywhere with no dead or low flow areas and they didn't appreciate it very much so a rest area is definitely needed for them to get away from the current. I have never checked the O2 level but Ik it's definitely not as high as it would be if the water were cold. I have a lot of surface agitation for O2 exchange so it's constantly oxygenated.
 
Well i guess the koralia allone would be able to take care of the dissolved oxygen since it is way over 10 times the amount of the water within the tank. Or do you also use air bubbles in addition??

So compared to your tank mine is one big dead zone :D But since i don't like my plants flying all over the place and am also quite sensitive to the sounds of big turbines, goonches are probably not for me.
 
My goonch actually prefers the slack. It never goes into the direct flow any more. I have a 800gph head pointed right at a nice rock spot and it sits under the log to the side. The powerhead slid a bit on the side of the tank changing the flow to hit that spot and it has relocated to a farther back slack zone created by the change in direction of the flow. It is about 78°f. I have tried higher and lower. It seems to act differently in both. Less active and stops eating. So for mine 77-78° it is. I think it comes down to the sp and also the fish itself. Mine I believe to be a sp. Indochina after many hours spent thinking and looking. I Believe it was Liam that put the thought out as Indochina first. As time goes on it seems to fit more and more.
 
The koralia actually doesn't add anything to the O2 level bc it is placed about 6" from the floor of the tank and pointed down. You need surface agitation to provide more O2 which is provided by the output from my sump as well as the water coming down from the overflow. My koralia is actually not loud at all. The loudest part is the water falling down from the overflow. I also don't have any airstones in the tank. I tried once but the pump was extremely loud.
 
Yeah 77°f would be my temperature as well... but in the summer it might go up to 85....

Well my 1060 gph flow-pump is responsible for the entire movement, it is pointet slightly to the surface. Not a strong movement at all but a slight movement over almost the entire surface of the 300gal.

Yeah air pumps are ridicilously loud.

Aw3s0me3 could you make a picture of the tank so it is possible to wagure the amount of movement?
 
It's really simple. The nozzle from the return is at the top and pushes water from the right to the left towards the overflow causing all this surface agitation at the top. The powerhead also starts at the right towards the bottom and pushes water to the left and when it hits the other end it just disperses all over the place. It's set up like a river system. That's it
 
Hmm well in the end it boils down to the oxygen level, but since it is difficult to measure i guess it's hard to find someone who kept bagarius successfull over a longer period of time and who measured this regulary.

Otherwise i could only try weather or not my 1000gph flow is enough or not....

I had over 10,000 gph in the 150 in which I kept my rutilus. She was happier than a pig in you know what in there.

And again a chance to identify the true Yarelli :D

The smaller one is definitely rutilus, the larger I'm not sure about.

Number 2

http://www.ebay-kleinanzeigen.de/s-anzeige/bagarius-yarelli-45-50cm/410314607-138-19987

the pictures from number 2 are not that great, ut this one looks like a true yarelli to me actually.

That is an extremely fat Bagarius bagarius.
 
Dammit i still seem to be incapable of telling them apart, i was shure the fat one was a true yarelli :(. Weull the owner of the 2 in the first link says that they are breathing absolut calm at 27°....
