robdog013 Posted July 17, 2007 Share Posted July 17, 2007 Hi Guys, I recently had a female chipokae and a female hongi spit, the fry were free swimming and I held them in a breeder net for a couple of days and then transferred them to a new 2fter tank, taht had a sponge filter and an airstone in it. In a couple of days they were all dead Where did I go wrong? SHoudl I have left them in the frysaver for longer? I lost close to 100 fry so If anyone out there could give me some advice. It will save lilve next time cheers Rob Link to comment Share on other sites More sharing options...

brendon Posted July 17, 2007 Share Posted July 17, 2007 I find fry are very delicate when young , and moving them is hard , but then again my mate milked his e yellows babys into a different tank with no fish in it and they all grew up nice and colourful Link to comment Share on other sites More sharing options...
robdog013 Posted July 17, 2007 Author Share Posted July 17, 2007 The fry were feeding in a breeder net in a different tank with catfish in it. I then moved the fry to a new tank one with no fish in it but the filtartion and heater were running for a weak and the water had been treated with chloromon and water conditioner. Thats as far as I know for water parameters. What other water parameters should I be looking for? thanks guys Link to comment Share on other sites More sharing options...

You filter and heater won't keep the bacteria alive if you had any there to start with. You would have been better served using water from your stocked tank and some of the media to kickstart the biofilter in the other tank. What killed your fish was most likely an ammonia spike because you didn't have enough beneficial bacteria in the new tank. They are very sensitive when small.

Thats as far as I know for water parameters. What other water parameters should I be looking for? thanks guys i would say an ammonia spike killed them, you need to check for ammonia,nitrites and nitrates. (first 2 are very important) Run the sponge filter for a month or so in a cycled tank before transfering it to a new tank with fry next time. When you say the filter and heater were running for a week, did you have some fish in there during that time or add ammonia to the water to "cycle" the tank? (not that a tank would cycle in a week) Google "nitrogen cycle" "tank cycle" etc. Hope that helps a bit Brendan Link to comment Share on other sites More sharing options...

robdog013 Posted July 17, 2007 Author Share Posted July 17, 2007 it was definetly a spike by the sounds of it, the sponge filter was a brand new one and there were no fish in it during this time. I shoulda used water from my established tank to fill it... thanks guys I know for next time Link to comment Share on other sites More sharing options...

By that I mean noodles/matrix/filter wool etc from an established tank. Link to comment Share on other sites More sharing options...
robdog013 Posted July 17, 2007 Author Share Posted July 17, 2007 So u mean next time I should take out one of my sponge filters from a larger tank, that has already been seeded and place it in the fry rearing tank.. okay cheers Link to comment Share on other sites More sharing options...
kilroy Posted July 17, 2007 Share Posted July 17, 2007 So u mean next time I should take out one of my sponge filters from a larger tank, that has already been seeded and place it in the fry rearing tank.. okay cheers exactly. If it is a from an established tank, it will still hold the beneficial bacteria and it will be a lot quicker for it to multiply than to start the cycling process from scratch. One large sponge filter should be enough for a fry tank. Link to comment Share on other sites More sharing options...

SOLEMNDRAGON Posted July 17, 2007 Share Posted July 17, 2007 would Geo Liquid be also beneficial for african fry or just better off with an already established tank ???? Link to comment Share on other sites More sharing options...
CThompson Posted July 18, 2007 Share Posted July 18, 2007 The tank/filter needs to be cycled so Geo Liquid won't help. The simplest way to do what you tried to do is to have the spare sponge filter in the breeding tank and move it across to the grow out tank when you water change your breeding tank. Put the water from this water change into the grow out tank, and then the filter. That way you will have no issues with water parameter differences or cycling. Bear in mind you need to have appropriate water in the breeding tank so monitor it. Just because the fish are breeding doesn’t mean the water is ideal. I should add you may have had a feeding issue too as they won’t have been able to pick over food in a fry net as a lot if not all will fall through. In addition as a first tank a 2’ is larger than ideal. The further fry have to travel to find their food the more of the food they eat will be expended on energy to find the food and not on their growth.

gingerbeer Posted July 18, 2007 Share Posted July 18, 2007 I would think that the biomass was not sufficient to poisen all the fish within 2 days. I am more inclined to look at basic water parameters - temperature, pH and hardness, and then at feeding habits. Water conditions is my best guess - especially as the quality of water is becoming a bigger issue as we have less and they dump more chemicals in the water. Sometimes the water we are taking out is better than the water we put in. Double dosing with the old prime at the moment is a good idea IMHO. (This from a guy who used to never use the stuff adn just splashed water around a bit). Water is worse up here due to the addition of chloramines. Lucky for me the landlord is looking at putting in a water tank. Steve Link to comment Share on other sites More sharing options...
