    So I have decided to raise my clownfish fry since we now have the rotifers and phytoplankton locally thanks to Reefaquatics. There is a lot of reading required lucky enough @jclaas took his time to summarise what I needed to do:). So below is my clownfish fry this morning +-9 hours after hatching..


    Just a funny story which I feel I should share,on Sunday evening 30 mins after lights went off I shined light on my tank and 100s of small larvae came to the light and I assumed them to be clownfish fry. I then collected them and put them in my larvae tank and put the rotifers to feed them. The next morning i woke up and saw those larvae were swimming backwards and looked like shrimp . What made me confused was that my eggs were still there and the clownfish were still cleaning them.I didn't have a problem with this as I had read somewhere that they might all not hatch at once. So I decided to just research on what clownfish larvae looks like and what I had didn't look like clownsish and after hours of researching and consulting I discovered they were probably mysid shrimps therefore I had to repeat the whole process last night of shining the light and collecting the "actual" clownfish fry "my grand kids".

    Fantastic, best of luck with them, looks like you've got everything sorted. Looking forward to daily photo updates. :D

    Just a quick one, have you blacked out the light on your heater? I just stuck some black insulation tape over mine.

    Thanks, no I didn't, I have the light covered by the suction cup holding the heater, that way the light is covered and thus the light is not emitted into the tank (i hope).

    thanks @MistaOrange, I hope it gets easier to maintain as they grow older

    Thank you all for the comments, @viper357 I now have 4 left, I made a lot of mistakes and as a result I lost most of them. So far I have learnt the following:
    1- you must not add too much phytoplankton in the fry tank since it makes it difficult to see the dead larvae which can quickly contaminate your water (I am even questioning if you should add it at all ).
    2. You must do daily water changes.
    3. You have to feed the fry at least twice a day.
    4. You need to adjust your air so that you do not have too many bubbles in your fry tank.

    Even though I have lost a lot of larvae, I have also learnt a lot and have realised that reading can give you the principles but you have to do it to understand the theory. As a result of my 1 week experience (lol), I'm confident that next time the survival rate will improve. Below are the photos of the remaining 4 which I took this morning.

    So the remaining 4 died yesterday :( But on the bright side I have time to grow my phytoplankton as I was running low. I think I need at least 30L of Phytoplankton as opposed to the 8 Litres which I initially started off with. So on my next attempt I should have more phytoplankton
    My clowns have also laid eggs and this is their 4th nest and I have been reading that the fist couple of nests are usually unsuccessful, should I wait for them to lay more nests before I start harvesting the eggs, @viper357 , @jclaas , @Andre@ReefAquatics and other reefers whats your take on this?

    Lastly I was just thinking that if I was able to attach the fry tank to my main tank so that I wouldn't have a problem of water changes. Is my thought practical if yes please advise on how best you can isolate and grow the larvae in your larvae display tank, I have seen some breeding nets on ebay, would they work for clownfish larvae? If this option works, it would resolve the issue of water quality

    connecting the tanks and the biggest issue would be to keep the fry from entering the tank connections, or being sucked into the grid protecting it.

    I doubt that connecting the tanks would work. Unless you got a very very soft gently flow going through.

    Thanks @RiaanP for your feedback, I was thinking of connecting the fry tank to the sump (where there are no wavemakers) then connecting a small pump with a control valve to feed water into it, see the picture below,, do you think it would work?

    with lots of holes then the suction could be OK. Just check out for blockage, that could either increase the suction on the remaining holes, or it can flood the fry tank.

    another option is to split the fry tank with a vertical divider. An the divider got a big hole in it, big as possible, with very fine net over that. Couple of months ago there was such a fry catch tank out there on on of the RSS feeds. It worked with airline, pulling water up and into the unit. So the flow was very gentle.

    So I'm now on my second attempt and today is day 15 and my clownfish fry are now going through the metamorphosis stage and are starting to look like fish,lol.. I have +-11 left and they are not dying anymore (I hope) Sadly I think I saw one with whitespot last night :( . So maybe connecting your fry tank to the main tank might not be a good idea after all but I will see if they are looking tonight.. I will upload photo's tonight.. On the bright side more eggs are hatching tonight, hopefully I will have a higher survival rate this time.
