Care and Feeding – Crawdads (Crayfish) as pets

Crayfish should be cared for exactly as you would tropical fish, however, you do not need an aquarium heater. In fact, cooler water is preferable for their survival.

They prefer their tank to have fish in it, so they can apprehend and eat them. This is included on the one hand to make your more successful with the crayfish, but also to warn you that with crayfish in the tank, you shan’t be successful with the fish.

Crayfish prefer to eat fish meat, canned shrimp, frozen blood worms, any kid of convenient and relatively “clean” meat. An example of an inappropriate food source would be fatty roast beef, even though it’s meat. We kept ours alive for their natural adult lifespan with little more than Sanfransico Bay brands’ “Prime Reef” served in chunks.

The ideal crayfish tank would have an inch of gravel on the bottom, some plastic and live plants such as Aponegeton bulbs, a daylength of 16 hours, using full spectrum lighting. The best bulb for full spectrum lighting is the CoraLife Trichromatic bulb. These are available for all the commercially available fluorescent fixtures.

An airstone would ideally be applied to the tank even if it has a good filtration system. The ideal filtration system for a crayfish tank would be a formidably sized sponge filter, perhaps the Tetra brand Bili(tm) or the Brilliant. Lustar V is also a good sponge filter.

Crayfish will hunt and eat by day, and night.

I set up my crayfish with caves to climb into but which permit me to see them sitting inside the cave. Simple slate pieces can be organized into a nice cave.

Crayfish of radically disparate sizes will fight and the smaller crayfish will be the loser. Even in matched sizes, as they mature, you may find a lost claw or other appendage due to skirmishes in the tank. Providing multiple caves and hideouts can be of assistance.

Good luck with the crayfish.

This is The LCD Screen Scope
We Did The Tutorial With. I did a twenty page tutorial (Here's the tutorial) with video, audio, images and even little parasite movies to show you how to use a microscope. 

This Filter is Good For BIG Dirty Tanks
I've been wrestling with water quality with the turtles. The sponges work GREAT, but in THOSE turtle systems where they eat MICE the poops are bulky. This filter can handle it. In "Tortu's" tank, it's got an 800 gph pump and it rocks. 

PraziPro for Flukes
They nailed it. Figured out the solubility and worked out the dosing. It works. 

Buy Some Good Koi?
No, this isn't really for the 'high end' collector y'all. But for someone who isn't near a decent garden center, here are "good-to-quite-good" Koi you will like at a very good price. I know these guys personally.

Best Food, Ever
It's made for (and I discovered it for) my Blood Parrots but the small size, intense color enhancers and excellent formulation make it superb young-Koi food. Oh, and it's AMAZING on color-cichlids like Flowerhorn and Blood Parrots. 

Pro Air 60 Aerator is a VERY high output air pump pushing my whole fish room (17+ drops), and I have one at home driving everything there, and I have one as a back up. 

Formalin Malachite (Not dilute)
There are formalin malachite preparations at 10%, 22% and 37%. There's economy in the concentrates. Hard to get Prime shipping because air transport is curtailed. This is a good value on 32 ounces. 

Topical For Koi and Pond Fish Ulcers
I like 7% tincture of iodine because it stains but it's hard to hurt anything with it. Used with a WOVEN gauze, this works well to clean and disinfect a wound. Only use ONCE. Do not 'repeatedly' scrub wounds. 

Confectioner's Glaze 
Is the way to bind a medication to fish food. Gone are the days of paste food and oil. The write up is done, it's RIGHT HERE.

Koi Health & Disease
Hopefully this link takes you to the newest edition by PRIME to get it to your house the fastest. 

I have over ten of these Titanium Heaters in my fish room and at home. They're a paradigm shift in aquarium heating. They're titanium and 400W for under $30! Whaaaaaaaaat?

CyroPro by Hikari is safe and easy for Anchor Worms and Fish Lice.

Whatever heaters you use, back yourself up with a temperature controller, it'll turn on, and off your heaters. If your heater seizes "on" at least the thermostat will stop a tragedy. 

LifeGuard by Tetra is a tablet version of a tame 'chloramine-t' or 'halamid' compound that's easy to get and good on bacterial infections, in baths. 

Antimicrobial
If you're making medicated feed for a larger group of fish, this will come in handy. Dosing is available in the site. 

For me, filtration-of-choice
For aquariums, even small Koi holding facilities or small ponds. These sponge filters are cheap, easy to clean, and they clear hazes very well when used with some Accuclear or similar.

Rubber sided, round, nettable tanks
Make great hospital or quarantine facilities. They SHOULD cost about $200-300 depending on size, but this, lower quality unit (while panned in some reviews) may be good. Don't overfill and make sure it's propped up.

1200 Watt heater, on a thermostat held securely above the waterline, works GREAT as a large tank heater. That's all I'll say because there's risk of electrocution and all that. But then, even in a bucket you could get killed. Sound like fun?
I have several of these ALLIED PRECISION stainless ones that are a couple years old. Working still. 

Potassium Permanganate 
500 grams could be a lifetime supply but it's 50% more than the 100g cost wise, for 500% more amount. Dosing is in the site and the book.

What Does Ajax Eat?
I looked for something well formulated, with meat as the first ingredient. Something UNDER $2/lb and something they could deliver for free. And this was it. He looks and feels great on it.
