just curious as to what the purpose of havn the tank floating in the other?

keeping them in a smaller tank restricts the space they have to swim
it may keep them a tad warmer too because the air is in contact with something before the water reducing the amount the water fluctuates???????
samir confirm will ya dude LOL

to prevent fluctuations in temp during wc and by putting a heater directly in such a small tank, also the fry were put there at wriggler stage and didnt want them sticking to the heater and suction etc. hence they all hung around the filter and so did the rotifers :D . oh and the tank wont move if there's no current in the outside tank.
you guys posted before me :lol: i have a heater small enough and EXAI is right :D

What type of rotifers were you using? Did you culture them yourself? They look like they are doing great!

were did you get the rotifers from
are they live if they are how do you look after them
did you feed them rotifers because the parants eat the eggs

the parents dont eat the eggs, its the other pair that does that. they were live and were being fed on chlorella paste, i forgot about them for a couple of days and now the're dead. i need to work on keeping the culture alive. the fry part was easy. next time i'll try the hikari frozen . i'm too lazy for cultures and stuff.

Samir post up your results after you tried the frozen rotifers. I would be very interested to compare.

hikari has frozen rotifers, i think they are the saltwater kind. i dunno if they will eat them, they sure ate the live freshwater ones.
Ben I removed them when they hatched. 100% survival rate :shock: :shock: :shock: didn't expect that. they started eating bbs in 5 or 6 days i think. I hope the frozen ones work as well, they do seem much larger so I'm not that optimistic. Lim & Wong (the guys that did the research) got 95% and 70% survival as opposed to 85% with parent reared. Survival for dwarf gourami fry (day 2-12) was rotifers 92.3% vs egg yolk 58%. I'll let you know next week (when i remove the cone from a couple of angry egg munching reds :lol: )
