tank246 Posted May 12, 2005 Share Posted May 12, 2005 Hey everyone I have about 6 fry electric yellows in a seperate tank its about 1ft wide and 1.5ft high. The fry dont seem to be growing very well. I am thinking its the size of the tank but may be wrong. Why arent they growing? Link to comment Share on other sites More sharing options...
DanceswithDingoes Posted May 12, 2005 Share Posted May 12, 2005 Two things for fish growth, water quality and diet, tank size will eventually play a part but not at this stage. I once read about a discus breeder who filled two identical tanks with discus, one with a hundred 2" fish the other with 30 2" fish and fed them the same diet, then measured their growth. Tank one had 4 x 20% water changes daily, tank two had one per day. After a month the tank with 100 fish had doubled the growth rate of tank with only 30 fish, reason = water quality, the regular changes increased the growth rate dramatically, point in hand change your water regularly. The second is diet, yellows are omniverous so can handle a little extra protien, so instar2 naupli, microworms and pureed prawn will all help to supplement their diet, but be warned with a high protein diet, fish waste is high and water quality becomes a factor, see point above Best of luck Link to comment Share on other sites More sharing options...
tank246 Posted May 12, 2005 Author Share Posted May 12, 2005 Thanks very much. I think i know my problem. My water changes need to be more frequent. How long between water changes do u reconmend would be the best? Link to comment Share on other sites More sharing options...
DanceswithDingoes Posted May 12, 2005 Share Posted May 12, 2005 As many times as you can manage per day (at least once), approx 20-30% each change. Link to comment Share on other sites More sharing options...

BaZ Posted May 13, 2005 Share Posted May 13, 2005 Ideally until they stop growing Every day is a bit steep for most of us. I try to change the water in my fry tanks once a week, but it is often once a fortnight instead. Dingoes is right, the more water changes you do the faster your fry will grow.

Lepperfish Posted May 13, 2005 Share Posted May 13, 2005 Do you change with water from the the parent tank of the fry? Or fresh tap water de chlorinated ect ect ? Link to comment Share on other sites More sharing options...
tank246 Posted May 13, 2005 Author Share Posted May 13, 2005 Thanks for the replies everyone I do a bit of both but havent lately. Should i do 100% water change from the parent tank? Link to comment Share on other sites More sharing options...
Lepperfish Posted May 13, 2005 Share Posted May 13, 2005 I wouldnt ever do a 100% water change. Even from the parent tank. I usually do about a 50% water change every 2 weeks from the parent tank water. Link to comment Share on other sites More sharing options...
BaZ Posted May 13, 2005 Share Posted May 13, 2005 I do 25% changes, always from the tap. I find using water from other tanks kind of defeats the purpose Link to comment Share on other sites More sharing options...
Lepperfish Posted May 13, 2005 Share Posted May 13, 2005 I do a water change on the parent tank then take the required amount of water from the newly changed parent tank and put the required amount into the fry tank. Link to comment Share on other sites More sharing options...
novafishy Posted May 13, 2005 Share Posted May 13, 2005 Would it be more feasible to weekly change 25% water from a 60L tank than a weekly 25% water change from a 120L tank? Link to comment Share on other sites More sharing options...
Lepperfish Posted May 13, 2005 Share Posted May 13, 2005 Wouldnt that be the same amount being changed? Both being 25% ? Link to comment Share on other sites More sharing options...
tank246 Posted May 13, 2005 Author Share Posted May 13, 2005 I do 25% changes, always from the tap. I find using water from other tanks kind of defeats the purpose ← This is what I am doing. I think I will stick to this rather than using water from the parent tank. Thanks for the help Link to comment Share on other sites More sharing options...
r.d.m Posted May 14, 2005 Share Posted May 14, 2005 i cant believe what im reading,4x20% water changes daily! imo totally unnesessary and with or current situation,completely irresponsable! Link to comment Share on other sites More sharing options...
BaZ Posted May 14, 2005 Share Posted May 14, 2005 I once read about a discus breeder who... Read the post properly Dances read about this guy, and the water changes were only being done that way to prove or disprove a theory. We do not know when these tests were done. Just because Dances posted this info recently, it doesn't mean the tests were necessarily done during our current water shortage. I once read about a guy who invented a petrol-driven motor car. Does that make him irresponsible considering the current fuel situation? Link to comment Share on other sites More sharing options...
r.d.m Posted May 15, 2005 Share Posted May 15, 2005 "As many times as you can manage per day (at least once), approx 20-30% each change". and if you read the whole thread he reccomends this at the present time , i'll ignore the pointless analagy as you and i dont have any control over it Link to comment Share on other sites More sharing options...
