but you might want the smaller shrip as the smaller fry might not be able to eat the bigger BBS never head the exclude air and refrigerate business before.

i had a small convict in with my RES turtle. convict was about 4cm long, turtle 15cm. the only thing in the tank was heater. filter and a small ordament that the fish could hide in. one day i noticed that the convict was missing a bit fron its dorsal fin then while i was looking in the tank the turtle had the convict cornered, until the convict turned around, stood its ground then gave the turtle a little bite, then the turtle left it alone ever since apart from the odd quick try.

wasnt there another similar thing to this not long ago with a forum user here?

so its only thursdays not monday-sunday? but yes im on the same page as cricket man, although the fish i buy dont seem to breed.

so that means goldfish arnt safe? :-? lol

for the heater bit i hung it inside one of my tanks to keep it warm, held it to the side using a clothes peg and had to lower the water level down to a point where P44 would be complaining

lol, like the one in the picture i just posted? i didnt know that the standard float switch would have hysteresis, seems like the better option to have just the one. wow 12v pumps are alot cheeper that i was expecting. just looking on trademe at boat stuff

my tanks are already drilled, well the 1m long ones are. im thinking of just running the drain part of the water change system, but not the fill bit yet. your talking about the pump outlet pipe (red one in the picture)? as i cant drain it straight from the tank to the drain outside because of the whole uphill.

my thought with the single float switch would be that it might just sit there and pulse on and off

when i used the upturned coke bottle it lasted about 3 days if i rember correctly, and lasted a day or two longer if i used natural sea water. for making a hatchery you: cut the bottom off a coke bottle drill a hole in the lid small enough to be a very tight fit for the airhose to fit in. poke the airhose in so it sticks in about 1-2cm into the coke bottle turn coke bottle upsidedown and fill with salty water, BBS eggs and pump air into it. but i rember a while ago amazonian made a brineshrimp hatchery but didnt give detailed enough instructions about how to make it, just a photo of it saying that he didnt use any glue. and i believe that he taught how to make it to the nelson/marlbrough fishclubs. anyone got anymore info about amazonians design?

Im lazy, wella atleast i admit it, and being human i go to alot of effort so i can do less later. so what im thinking is i will start with the large tanks first. what i want is an automatic waterchanger thing. but i think i will make half of it first, the drain half. that way i can just throw a hose/pour buckets in there to start with and the water will leave the room. but thats where the problem begins. i cant simply make my tank drain hole flow up to the window to make it drain onto the back lawn... can i? so using valuable work time ive been drawing and thinking about this and think that having a bin under the stands would be best for the tank to drain into. and bacause i can i was going to build a control unit and put a pump in there, so that when the bin fills up it pumps out onto my crappy long lawn to make it grow more! this would also allow me to add the other half later when im motivated/ rich enough to add in a drip system into all the tanks. ive got a picture but i cant upload it from the work computer. now in this waste water bin i was thinking of having it so its got two water levels, an upper and a lower. when the water reaches the upper level it turns the pump on until it reaches the lower water level and shuts the pump off until it hits the upper level again. or would it be better just having the pump go on and off acording to a single float switch? i think thats enough ranting for now

photos!

i always go to the local spca, could be worth going for your first look

yea pot should work (i dont breed discus but have seen this question before) believe you need to plug the hole though so the fry dont dissapear down there and get lost "if you make it idiot proof they will make a better idiot"

i did my tank with a layer about 3cm aquatic mix, then a little bit of left over silicone sand (only a very thin layer that bearly covered the aquatic mix, then i put on about 4cm of fine gravel. i used some brown fine 2-3mm gravel from hollywoods. and defenatly pour the pucket of water onto a plate, slowly as you dont want to disturb the gravel too much and churn up the aquatic mix.

ive seen a diy cone made from tiles siliconed together to make an 'A' shape

could try putting poly on the back and sides to help keep it maintail temp and cover it with something at night. HTH

60db is about the same volume as normal talking volume, thats adult volume not excited child volume

490 tanks run from the one huge pump. well guestimate using ryans figures from his airpump and airstone numbers

but thats 2L of air not water, and if your running air filters then your not going to get near the 4x total tank volume of water put through them are you.

short answer yes i think they are. but ive found that the PK ones are alot hardier and active than the long finned variants

is this the tank that the jar was in? just trying to think of what tank this is.

wow thats really nice!

that's quite good, hows the heater going? is it on all the time or has it prity much stopped?

ill ask before someone else does..... what size is the tank? i would go with cories as they stay smaller and arnt as messy
