Peter_Gun_Riff Posted January 19, 2004 Share Posted January 19, 2004 ive notcied that my fry take so long to grow and i was wondering if a 3ft tank would be ok to grow 20 or so fry up at a time to a good sale level? Link to comment Share on other sites More sharing options...
Mazimbwe Posted January 20, 2004 Share Posted January 20, 2004 20 fry in a 3ft tank...should be plenty(read as: More than enough) of room, depending on the species, to get em up to a large size for sale. Link to comment Share on other sites More sharing options...
Peter_Gun_Riff Posted January 20, 2004 Author Share Posted January 20, 2004 red empress and peacocks will be the species in the tank Link to comment Share on other sites More sharing options...
Mazimbwe Posted January 20, 2004 Share Posted January 20, 2004 My experience with Peacocks is that 3ft tanks are huge, in relative terms, as a Grow-out tank. I have not spawned any Protomelas but other mouth-brooders of similar or larger size that I have spawned are fine in tanks that are not that big(3ft) so I think you should be OK. What size are you planning on growing them too?? Also... ive notcied that my fry take so long to grow...do you put that all down to the size of the Grow-out tank?? What else have you tried to improve growth and what size tank have you been doing it(growing fry) in?? Link to comment Share on other sites More sharing options...
Peter_Gun_Riff Posted January 20, 2004 Author Share Posted January 20, 2004 i had 5 peacock fry in a 7 gallon tank and i had an auto feeder on them while i was at school(school holiday atm) and they got to about 2cm and stoped growing. ill be getting the 3ft soon i hope as i have a few empress fry on the way. im hoping to get them to about 3-4cm mark to sell.

Mazimbwe Posted January 20, 2004 Share Posted January 20, 2004 Maybe their growth-rate was effected by the type of food you were using or the number of water-changes, with what(?) water...just a thought. Link to comment Share on other sites More sharing options...
Peter_Gun_Riff Posted January 20, 2004 Author Share Posted January 20, 2004 they were on flake food and once a day choped black worms. i did a 30% water change a week but when i get the 3ft i hope they will gorw alot faster and bigger and the 7gallon will become a brine shrimp hatchery Link to comment Share on other sites More sharing options...
Josh Posted January 20, 2004 Share Posted January 20, 2004 Hi Peter_Gun_Riff, my grow out tanks are only 2 footers and my fish grow pretty fast. I have 16 2 cm Ps. saulosi and 11 1.5cm E.blues in there. I also noticed that if you keep the temp up (around 28 deg) they seem to do better. I only do weekly water changers. I also feed 3-4 times a day with a combo of HBH fry bites and HBH flake Josh and Evelyn Link to comment Share on other sites More sharing options...
Peter_Gun_Riff Posted January 20, 2004 Author Share Posted January 20, 2004 how long did they take to get to that size? Link to comment Share on other sites More sharing options...
Josh Posted January 20, 2004 Share Posted January 20, 2004 They are both about 4-5 weeks from the time their egg sacks where completely gone. so say there about 6-7 weeks old. I know I had troubles at first with the same size tanks, but I put it down to, a combo of, poor feeding habits ie. not enough times a day, and the temp being to low, around 24 degs Josh and Evelyn Link to comment Share on other sites More sharing options...
