For those of you who might want to know, I thought I would give a little insight on my feeding and husbandry regimen. Dwarf seahorses are definatly high maintenance and take a bit of time to care for. Between my 120 gallon reef tank, and this little 5 gallon seahorse tank, I spend about an hour a day just on feeding and maintain the food.
This is my three stage brine shrimp hatchery system. The one on the left contains hatched brine shrimp that are being enriched with Dan's feed with probiotics. The middle one contains hatching or newly hatched brine. and the one on the right contains fresh saltwater that is being oxygenated. The system is set up on a rotating basis. Every day around 5pm I sieve the enrichment vessel and the newly hatched through a 120 sieve and transfer them into the fresh saltwater vessel. I then add the dan's feed to this (which I blend up using a magic bullet). I wash and clean the 2 dirty vessels, and refill them with saltwater. to the middle one I add 1/2 teaspoon of decapped brine shrimp and the other one I let bubble to reset everything to the beginning.
At 8 AM the next morning, I turn off the bubbles on the enrichment vessel, give it a few minutes to let the brine swim to the top, then net out the enriched live baby brine, rinse them in some RO/DI water, and place them into the feeding vessel next to the seahorse tank. I also put about 5ml of phyto (ocean magic) in the vessel so the brine have something to munch on in the vessel.
Then with a program through my apex, a pump kicks on at 11AM, 4pm and 9pm, Causing the feeding vessel to overflow into the seahorse tank and thus feeding the seahorses 3 times a day. I was doing it 4 times a day but it seemed a bit much. Durring those time the apex also kicks off the skimmer and filter for about 20 minutes allowing the seahorses to eat freely without the brine being sucked into the filter side. Then the filter and skimmer kicks back on, cleaning up the mess, usually there is brine swimming for about 2 hours on the seahorse side, before the filter gets them all.. I then rinse and repeat this every day, and it seems to be working great so far. Since I am a fireman I work for 48 hours straight. The night before I go to work I fill up the 2 right vessels with saltwater and let them bubble overnight. In the morning before work I scoop out a generous amount from the enrichment vessel and put in the feeding vessel, and add 1/2 teaspoon of the decapped eggs to both the other vessels. I do this in case one of them crashes while I am at work I will have a backup. My worry is when I get home from work having enough brine alive to be able to feed, because I won't have any fresh brine for about 20 hours after arriving home. So far there has been plenty of brine alive when I get home and it hasn't been an issue.
Now for the tedious and nerve wracking part. For husbandry I do a 40% water change every 6 days, the day before I go to work. I know it sounds like a lot but in a 5 gallon tank its only 2 gallons. The hard part is getting everything perfect. I triple check salinities and temp before doing the water change. Doing a 10% in my 120 DT, heck if the salinity is off a little or the temp is a few degrees higher of lower, it won't change a thing in the DT due to the volume of water, but on this little guy even a 1 degree temp difference causes a pretty big spike. Temperature is the hardest part. I keep the seahorse tank at 75 degrees + or - .5 degrees using a heater and a fan hooked up to the apex. In the summer around here the fresh saltwater hangs around 80 degrees so I always need to cool it down which I do using icepacks in double baggies. Its a pain because if I am not checking the temp every few minutes I will overshoot the target temp then I have to heat it back up. I first take that little syphon brush I have and just brush the whole tank off to get the debris free floating and let the filter and skimmer suck as much of it up as possible. I let it settle a little bit then start a syphon and Suck the as much of the debris out as I can through the filter sock. I then pour this water back into the tank. I do this because with 2 gallons I am not able to get all the dirt and debris out and it gives me one more suction out. I once again let it settle a bit and then do it again, once again through the filter sock. I set this water aside and refill with fresh saltwater. I then take the filter media out of the filter, rinse it in the old socked saltwater, replace the little bag of carbon I run in the filter, rinse the skimmer cup and put it all back together. Usually my temp does not change at all and I maintain a salinity of 1.024. On the day I get home from work I empty and clean the feeding vessel (there isn't too many brine in there at this point), refill and restock with brine and get ready to do it all over again. Its funny because the ponies seem to be getting used to this system and when the see the little scrub brush enter the tank they just swim in a circle around the tank, always staying on the opposite side from where the brush is. Before I start I find the baby of the group (which can be quite challenging sometimes) as she is the one I worry about sucking up and not noticing.. Its probably going to get real interesting when I have a slew of babies but I will deal with that when the time comes.
The tank sits next to a window and I allow indirect light in from sunup to sundown, and my little aquamax nemo light provides artificial lighting from 2pm to 10pm. I also added the oxydator mini and it seems since doing that the diatom bloom is going away and that the horses are much more active, so I am wondering if I was a little O2 deficient before. It also could have been a PH problem (high in CO2 and low O2, which I don't check because I figure with the amount of water changes there isn't really much I could do about it). Once a month I give them a treat by adding Apocalypse Pods from algae barn which I was hopping would start a colony on the filter side but I think they all get eaten up too fast. I buy pods and phyto once a month for my DT to keep my mandys fat and happy so I just get an extra bag to add to this tank sort of as a treat.
Anyways, if you have any questions or suggestions feel free to hit me up. I don't think I can do much more but anything to make it easier is always welcome. As you can see this definatly isn't for a hands off aquarist and it takes a bit of time and effort.
