Putting the check in the mail for bullhead catfish. Ordering them because I've read they are tough and taste OK when raised in clean water. I need to find reasonably priced feed but I'm in the city so no agriculture or pond stores nearby. Thinking of trying cat food. Any thoughts/advice?

Tractor supply looks like there may be a couple of stores less than an hour away from city center. Waldorf and out rt 4 towards the east and another southwest. They will likely have 30+% protein fish food.

I used aqua organic fish food last year with bullheads and they adapted pretty well to it. I used bullheads from a local pond. Due to some timing circumstances I didn't eat them, but I hope to this year. They are very hardy. Mine ended up out of water last year due to an overflow in a grow tube. They all survived.

Good luck.

Here's some Purina information on what they have. Doesn't go into much detail but might help a bit.

http://aquamax.purinamills.com/aquamaxfishdiets.htm

Couldn't find much about Skrettings fish feed here in the USA. The big producers don't seem to want to make analysis information easy to find online :dontknow:

I went ahead with the koi food. While I don't like fish meal as the first ingredient for sustainability reasons, ill start with it. I figure it should be a safe food to keep things going while I find an alternate.

I bought some gear for electrical backup as follows

4 amp waterproof battery charger/maintainer
26 amp-hr battery
Low power inverter
Battery box

Simply plug in charger and connect charger and inverter to battery.

This should be able to handle my circulation system driven by my 3w air pump plugged in continuously, which provides auto back to sustain fish in power failure. I would then manually plug in pump with adjusted flood/drain timing to minimize electrical usage. Once operational, I may also test to see if it can handle my pump being directly plugged in (60 w for 15 min each hr). Not bad for about $100.

Comments? Anyone see any problems with this plan?

Bullhead arrived the other day. They can't seem to figure things out. They hide out in a corner. A few will come when I feed. They seem to like the fish flakes I've been giving the goldfish. They will take the pellets into their mouth then spit out. I think I will have to break up the pellets and mix with flakes until they get bigger.

Also two dead this afternoon. Lets hope it was related to the shock of transportation.

I would highly suggest moving to Purina's aquamax. Koi don't need the amount of protein that catfish do.

Found my problem. After a couple dead fish, discovered my nitrite is high. Off the charts. I thought I was cycled because ammonia had been zero. I gues not enough for all the new fish. I wish I would have been more diligent at testing.

I've turned the pump on more frequently 45 on 15 off instead of 15 on 45 off. Stopped feding. I've done a couple 10 percent water changes, one each day. I don't want to salt because my strawberries are growing well. Any other suggestions? Temperature is about 20C pH 7.0. Ammonia hard zero or 0.25 ppm.

Also water is cloudy because the bullhead starred up sediment on the bottom of the tank. I can't see the bottom. How likely is it that some dead fish down there? Do they always float?

Scott,
You can salt up to 1ppt without affecting strawberries which will help fish with stress. What are current nitrites levels? They can quickly cause brown blood disease and kill fish. It is quite possible you have additional dead fish, and it take a while for the body to decompose enough to make it float. By the time it floats, you will have a very large ammonia/nitrite spike...

Nitrites are more than 5. I didn't have time to dilute and measure again. So far ammonia and ph have been ok. Any ideas on how to search for dead fish at the bottom of a cloudy tank? The options I'm considering are getting in and feeling for the fish or drain enough so I can see. I'm not really liking either option.

At that high level, your fish will be dead soon (basically suffocating because they can't uptake oxygen). You need to use a net and pull all fish out and get them into another tank asap if you don't want to salt. Otherwise salt to 3ppt ASAP. And get in and get out any dead fish or use net. Make sure net is soft so it doesn't damage the sensitive skin on the catfish.

Thanks for the advice. I haven't been home all day.

When I measured this morning, it looked closer to 1 ppm but its hard to read the nitrites.

I salted to 100 ppm. All I have on hand is kosher salt and I didn't know how bad the anticaking agent would be.

I also thought of a way to search the bottom by covering the end of a pvc pipe with clear plastic. Ill try this when I get home.

Again, thanks for the advice. Ill update status later.
