they aren't smart it's just cupboard love

so you are better to cycle with a few fish and water changes then

:slfg: i think it is a common complaint with fish

how are your water parameters and when was your last water change

yes it is they have a hang on back skimmer on trade me at the moment too

somebody tattooed stripes on a goldfish

the lol was from a few years of keeping gold fish and not had a problem with feeding from the surface i have seen problems with gas in the gastrointestinal tract though which can be corrected sometimes by feeding green peas i suppose if the oesophageal sphincter was weak it could allow air into the digestive tract or many commercial goldfish foods contain wheat and soy which can create gas in the colon caused by bacteria fermenting the starch or sugars found in them digestion of these starches by animals requires an enzyme produced by bacteria present in the gastrointestinal tract producing hydrogen, methane and carbon dioxide it is also possible that high nitrates can affect the vascular mechanisms for controlling the amount of air in the swim bladder

:slfg:

if they did breed there is a good chance young will be sterile

you need to quantify your statements as you make them back on topic you can cycle a tank using chemicals to provide food for your bacteria to establish or you can use a few fish to do the same thing you can add chemicals to lower your ammonia etc or you can do a water change the slower you do the water change the less chance of shocking the fish

i use them on fresh and salt water

Need a stickied thread on the emergency management of toxic comments on the forum so much for first do no harm

conjecture and assumption are wonderful words for a newbie it needs to be straightforward and in layman's terms your average new hobbyist doesn't want long dissertations but a simple answer

it is rarely when you are trying to sort a cycling problem that the source and tank parameters are the same so massive changes can kill

does this help? http://www.calctool.org/CALC/eng/civil/hazen-williams_g

or think they know better

used to use them to direct coolant in the CNC lathes

for the price of a decent new canister filter you can get 3 times the media into a sump

interesting to see scoliosis in the splits and not showing in yellow tads

the brain of a fun guy :rotf:

sticking those 2 statements together may be read as an inference on the posters part that the lack of testing the water killed the guppies

how is their blood pressure?
