Thanks caryl and pheonix! I have never bred rams before so its a new challange to keep me occupied. I absoultely love the fry, you can see their little ram personalities come through almost as soon as they are free swimming. Very inquisitive little things
I am still learning myself, and it was a bit of a rough start where i was losing most of my wrigglers but this is what works for me (at least at the moment...technique still needs to be perfected to get a better survival i think):
-eggs (on rock) get moved into a ~6L tank with a 25W heater and airtstone situated really really close to eggs (because its not particularly strong) so that there is enough water movement. Quick air exposure during move doesn't seem to affect egg hatching...water in little tank is from parent's tank. Make sure you don't take eggs too soon before the male gets a chance to fertilize them all.
-meth blue is added as per instruction on bottle, but for the next 1-3 days after (until wrigglers are a bit more active), i add 1 more drop per day to keep colour strong
-temp set at 30C, do not allow to get any higher....32 killed all my wrigglers the first time (30C is also the temp of the parents tank)
-once wrigglers hatch, try to just let them be, remove rock and also pipette out any material/egg casings from the bottom that look like they maybe going fungusy, i do not do any water changes yet. i found that my electric blue ram wrigglers are WAY more active then blue ram wrigglers from the moment they hatch... will have to research this further
-as wrigglers grow, i start to gently pipette the bottom and remove any that may have died and just create a little movement so fungus doesn't build up anywhere the wrigglers are crowded....really its just me fiddling with them cause they are so cute - i stop adding the 1 drop of meth blue per day at this stage
-once free-swimming, i do a little water change (15%) using water from their parents tank and add ALOT of java moss into the tank...
-i wait till they are a few days older (a little bit better swimmers) and add a bit of infusoria and also some microworms. Once i think i added the food too early and a lot of fry died the next day...maybe some of the critters attacked them?
-when they look like they are big enough to eat decap, a few days later, i start adding that. Remember to pre-soak it!
-i don't do water changes every day, but i am also careful not to over-feed too much. I found before when i was trying to keep the water really pristene with daily 30-50% water changes more fry died...they seem to be more sensitive to water change then a bit of debris build up. Plus its hard not to suck them up when cleaning the bottom, and if you do this too often, they can get stunned and die from injury (especially if you do it when they are still wrigglers...yoke sacs can easily rip)
- i do a 15-20% water change every ~3 days, siphoning up any gunk. Inevitably i do suck up some fry but that is why i collect the water in a large white bowl so i can see them and pipette them back into the tank.
- once they are big enough not to fit through the spaces/net of a breeding trap, i move them into the parents tank, with java moss in the trap and do 50% water changes every 2 days (because i also have juvi discus in this tank). I feed them mostly decap 2-3 times a day with microworms every couple days
After this, it is still uncharted waters for me! I hope I can get a lot to survive into juvi stage! Will post pics as soon as i can!
