Nitrite spike

I have since last Wed gotten a Nitrite spike, rising from less than .15 ppm to 3 ppm.  I think it may be due to over feeding, although I don't find much food residue on the bottom of the tank.  Not…Continue

Brad

Keep in mind if your water is flowing through flood and drain media beds and towers, the air temperature is going to have a huge impact on your tank water temperature as you circulate the water around.  And chilling water for the trout is going to also chill the water for the whole system and catfish don't eat as well in cold water so make sure you pick a temperature that will still be suitable for your catfish to eat and grow too.

Hello

I'm Brad out of  Oceanside, Ca. starting up my system, going to be using  two ibc 275 FT w/ a 300 gal sump, four raft beds - 4' x 8'  eight 1/2 barrels w/ gravel, flood & drain  ten vertical towers.

Swimming up and down a corner or hanging on one particular area of tank wall or hiding in a pipe are all pretty normal behavior I've seen in some catfish while in other situations they will swim round.  In cool water like 50 F they are minimally active.

Looking to Purchase Channel Cats in NJ  

Comment by Bob Campbell on November 19, 2012 at 10:54pm

Thanks TC.  I'm sure the water and DO are good.  It must be they are scared.  They act like autistic fish, swimming up and down in one corner.  I have one that lives in a pipe; I rarely see it leave.  Oh well they are nothing like Tilapia but they are growing bigger so I guess they are eating.

Make sure there is plenty of dissolved oxygen and the water quality is good.

In the outdoor tank at 50 F they are likely not eating much at this point so make sure you don't over feed and that uneaten feed is not building up in the tank.

The indoor aquarium fish I would expect to be eating but they may be waiting till they have privacy.  Catfish can sometimes be scardy cats.

I have 6 - 2.5" catfish in an aquarium at 80F, and 22 more in an IBC outdoors at 50F.   I have never seen either eat when I feed them.  They are getting larger, but they constantly hang out in a corner of the aquarium and the others crowd into the drain hole of the IBC. 

I've had these fish for at least 5 weeks so I assume they eat something, and I continue to feed them even though they seem to have no interest.

Is this common?  I can't even spark their interest with a high quality fry food I bought from the pet store.

When I get new fingerlings I often get 5 or 10 lb of higher protein smaller pellet or grain size feed from AES to feed them until they are big enough for the Aquamax 4000.  You can grind the aquamax up a bit so it is smaller and sinks a little more for little guys but a higher protein feed for the first couple months often helps get them bigger faster and off to a good start.  Just make sure you have enough filtration to handle the heavier load from the higher protein feed.

What do you guys feed your fingerlings? I'm buying 4-6 inch channel cat fingerlings. I'm currently feeding my adults 1 cm round Aquamax pellets. Will these break up in the water and still work for fingerlings?

My catfish were edible size in just a few months.  They look to be several pounds now in 10 months, easily 3 pounds.
