Kremis's 28 gallon nano cube

[Kremis]

Hey all! For those who don't know, my name is Kyle, and I have been keeping reef tanks since I was 11 lol. I have two tanks, a 180 gallon and a 28. This thread is about the 28. Enough about me, here is some about the tank! To start out, I will first say that the main residents of the tank are 3 spotted garden eels and 2 h. erectus seahorses. I have had the seahorses for about 8 months now, and one of my garden eels for a month (you can find my story about him here - http://www.reefcentral.com/forums/showthread.php?t=2599865 ) and I just got 2 more on saturday. If you can't already tell, I have an interest in keeping very odd looking fish lol.
Current stock list:
Fish:
2 Erectus seahorses (ORA)
3 Spotted Garden eels
1 Pygmy Perchlet
1 Yellow clown goby
Corals:
Green nepthea
Sun Coral
Green mushroom
green clove polyps
green star polyps
Green birdsnest
Bird of paradise coral
red montipora cap
Pulsing xenia
Green trumpet coral
Inverts:
Red tuxedo urchin
peppermint shrimp

And I Have a red marco algae in the tank for the seahorses
Here is a short video of 2 of my garden eels feeding. The one close to the camera is the one I have had for a month, and the one behind (smaller one) is one that I just got.

Here is a video of the front of the tank, same feeding.

My third garden eel a few hours ago swam into the overflow for some reason, I had to go back there and get him to come out by himself out of the overflow. He then settled back into the "pit" in the middle of the tank, which is annoying, because the idea is for them to settle in the front, but im sure he will move on his own. All 3 eels are eating well. The tank is turning 4 this year.
I seem to be one of the youngest members of RC. Anyone else around my age out there? :lolspin:
Tell me what you think! Any positive/negative/any feedback is appreciated!

Latest death: tangaroa goby
Latest fish addition: 2 spotted garden eels

I am a bit concerned that the tank is overstocked and you will be unable to simultaneously fill the needs of the eels and seahorses. The pygmy perchlet may be too aggressive for the seahorse and clown goby. I don't see any good hitching spots for the seahorses. Finally the tank is way too small for 3 garden eels. They need a specialized/species only tank of 100 gallons or larger, and if you have more than 1 male they might fight

I have had the perchlet with the seahorses for as long as I have had them, no aggression what so ever. The seahorses mainly hitch on the red macroalgae that is under the green nepthea, also a goniopora like piece of wood in the back (its black / brown so not very visible) The sand bed in the front is 6-7 inches deep. I feed the seahorses mysis shrimp and the eels get cyclop eeze. The nutrient levels get a bit on the high side, thats why I am running a efficient protien skimmer on the back and do very frequent water changes. I have not seen any aggression so far, but if I do I will promptly take the aggressor back to the store. The only negative part about the seahorses that i see is that they need seperate feedings and sometimes go over to where the garden eels are and the garden eels get scared and hide for a bit. Thanks for the feedback!

I am pretty sure 1 garden eel died.
On monday, the 2 of the smaller ones settled an inch from eachother, were eating, and everything was fine. A few hours later, my mom called me down and said one of them went through the overflow and is in the back of the tank. I went in there with a flashlight and sure enough, he was in there. I managed to get him to come out on his own, and he went back out and settled in the sand. The next day, there was no sign of him. I havent see him to do this day, and am pretty sure he died the other 2 are still doing very well and eating like pigs. I can still hope that one day I will walk down and see the missing eel out and about lol

That's too bad. Have you made sure that problem can't keep happening?

 

[Kremis]

I tried to put some mesh over it, but it restricted the water flow too much. I believe that it won't happen again, because garden eels freely swimming is pretty unusual. I am going to try more solutions this weekend just to be safe

So today I stopped by my LFS and what do you know, they had 3 splendid garden eels! I picked up 2 of them and brought them home. I realized that the small space I have wouldn't fit, so I expanded my sand bed. I will not be adding any more garden eels (or fish in general) to the tank (if these live, at least) because 4 is really pushing it for a 28 gallon.
They came into the store yesterday, and seemed to be in good condition. Both burrowed into the sand in less than a minute after being in the tank.

So far, 1 of the splendids has poked its head up. The other one is still hidden

 

[Kremis]

Update: 1 of the plendids is braver than the other, almost always has his head up. Still hasnt touched any food. The other barely sticks his nose out sometimes. I know hes alive because of the hole he leaves lol. No aggression what so ever yet
