I just recently found out that you can actually have an octopus as a pet! lol i had no idea but now i want one!

after about 3 years of wanting a seahorse I finally got a job and bought myself a 29gallon tank (i dont have much space in my room for anything bigger) there was a post about keeping seahorses with octopus which stated that certian types of fully grown octopus and fully grown seahorses will get along. ill assume the only ones that would get along will be very small octopus. thats good all i want is a small one because my tank is small aswell, but whats the name of it?? and would it be ok in a 29 gallon tank?

i dont want to overly fill my tank with plants and rock because that leaves less room for the inhabitants (ill get a little cave or something if i get an octopus) right now i have only about 2 lbs of live rock and a little treasure chest cave thing. i am in the process of cycling the tank.

this is all i want for the 29 gallon tank
-a seahorse
-a clown fish
-a starfish
-an octopus

seems like alot to me, but a clownfish and the starfish are small. and i dont plan on cluttering my tank with unnessesary rock and stuff anyway i would like to know if a mini octopus would bother any of these. and if there is such thing as a docile mini octo.

thanks

hmm alright another question, over the past 2 or 3 days ive noticed my live rock is turning deep orange, at first i thought this was cool but upon closer inspection i found that the orange stuff is all over the crushed coral gravel, and on the top of the filters.. :S it kinda looks like dust or algaie but its bright orangie brown.. all i have in my tank is:
an undergravel filter, crushed coral for gravel, 2 lbs of live rock, a small fake plant, a hard plastic hollow treasure chest thing, heater, thermometer, filter, salinity thing, and above is a light.

like i said im in the process of cycling the tank, is this part of the cycling? am i keeping the light left on for too long? is this a bad thing? i did water tests, the ammonia is increasing like it should, nitrite is still quite low, around .01. the salinity is fine, the ph is fine, i think the ph test is a little hard to tell because i can only see it in the aquarium lighting, in my room lighting it looks brown instead of blue like its supposed to.

A 29 gallon would probably be suitable for a pygmy octo, but I don't think the tankmates would be a good idea. The octopus would probably get along alright with the starfish, but I think mixing them with any fish, seahorses included, isn't a wise choice. Octos seem to be pretty bipolar with fish. Either a) they will kill everything moving or b) they will be afraid of everything moving and never, ever come out of their den.

At $50++ for a captive bred seahorse, it isn't an inexpensive experiment. Seahorses also prefer a bit different environment. I believe they usually like taller tanks rather than wide ones and like a lot of macroalgae to anchor themselves to.

would it make a differance if i had the seahorse first? or if i added it after the octopus settled in? like how its easier to add a puppy to a house with a cat than it is to add a kitten to a house with a dog, sort of thing?

Also, clowns can be a little too aggressive for seahorses and stress them out. I couldn't imagine keeping horses with an octo, I wouldn't imagine either would like the situation much.

29 gallons is not a suitable amount of real estate for ONE octo let alone and Octo and something else.
Octos MOVE mine was constantly roaming around

Mizu, you're absolutely right about tank size for most octos we keep. However, some of the very small pygmy octos like O. mercatoris could be kept in a 30 gallon and have a lot of room. However, they're not easy to find.

i only want a little pygmy octo.. and the clownfish would be the false clownfish (the most docile kind) ive heard they are no problem with seahorses.. :frown: it seems everything i want wont go with anything else. seahorses ive been told shouldnt be kept with anything else, and most starfish ive been told can be harmfull to things, and now an octopus seems a bad suit for anything aswell :frown: im gonna be stuck with 30 gallon tank with nothing but a clownfish :frown: *sigh are you sure even a little pygmy octo would eat a seahorse??

I won't say it will necessarily eat it, but I guarantee you neither will be very happy with the other one present. Both seahorses and octopuses like their own dedicated setups. If you're interested in clownfish, why don't you get two? If you get two that are the right sizes they will grow a pair bond. Single clownfish can grow kind of lonesome.

I THINK YOU WOULD PROBABLLY BE THA HAPPIEST WITH SEAHORSES SINCE THATS PRETTY MUCH THA REASON YOU GOT THA TANK RIGHT? AND YOU WILL PRETTY MUCH ALWAYS BE ABLE TO SPOT THEM UNLIKE OCTOS, YOU WILL PROBABLLY END UP STRESSING OUT BECAUSE YOU WILL RARLEY SEE IT AND THAT WILL LEAD TO YOU POSSIBLY ENDING UP TEARING YOUR TANK APART TO FIND HIM. THAT OR HE EXCAPED AND THATS ANOTHER THING YOU GOT TO OCTOPROOF YOUR TANK TO HAVE ONE OR ELSE THEY WILL MOST LIKELY FIND A WAY OUT IF NOT SEALED PROPERLY! SO IF THAT LEFT YA THINKING YOU WANNA START WITH SEAHORSES THEN I WOULD SAY THATS THA BEST WAY TO GO! AND IF IT DIDNT SWERVE YOUR PATH AWAY FROM OCTOS THEN I WOULD SAY DO ALOT OF RESEARCH MAN AND PRAY TO GOD YOU CAN FIND A PYGMY CUZ OCTOS GET BIG FAST! OH YEAH AND ONE MORE THING THAT BROWNISH ORANGE STUFF GROWING ON YOUR ROCK AND GRASS IS ALGE DONT WORRY MAN THATS JUST THA START OF YOUR STRANGE OCCURANCES THAT WILL COME FROM YOUR TANK ONE DAY YOU WILL SEE A FEW SNAILS ON THA GLASS AND THA NEXT YOU MIGHT SEE A STARFISH! WELL GOOD LUCK TO YA ON YOUR TANK AND MAKE YOUR CHOICE WISLEY!
