So this is my "negative" post. It's more meant to be a "here's why this probably won't work" as opposed to a "I hate this and everything it stands for" post.
Seahorses: need a lot of extra care. It just comes with the whole "I'm a somewhat primitive fish with a really bad immune system" thing. Typical reccs for temperature are around 72-74 F, which most people think are too cold for their reefs. And they're also just...a lot, when it comes to basic care (feed them every day, keep their water clean, etc. but square that). My vote's a no on the seahorse.
I hear you, but I feed my display 4-5x day. I have 4 active Tigriopus californicus cultures going, which I believe are a suitable size for the seahorses I would be looking at. Aside from the temperature, I think they would do well. I’m also running 80 watts of UV.
Not trying to yuck anybody's yum, but I also feel that anemones and clownfish are just...overdone. Yes yes, fascinating nemos, they get into the hobby, but like...ok I get it, textbook symbiosis that still requires more research. Also aren't ritteri's (Heteractis magnifica) supposed to be the hard to keep anemone?
Yes, Ritteris are among some of the ‘harder’ to keep nems. I can adjust flow/lighting to whatever it needs. I would be looking at a pair of wild latz, mccullochi, or percula.
For the octopus (not necessarily the cuttlefish), I hear that the plumbing has to be super secure. I would hate for your newly acquired octo to get into the piping, and start devouring your fish. I also think I've read that octopus need to be kept at cooler temperatures (mostly because it's a lifespan kind of thing). Octos and cuttles tend to have a very short life span as well...and need live food....
As I mentioned above, im not considering an octopus due to the tank restraints and risk.
Mantis Shrimp: I guess they'd make a good "pet" shrimp? But that's an awful lot of height for a mantis, which might mostly only stay in one spot, right? If it was a 20L, then I could maybe see it, but a 29 gallon seems too tall in my opinion.
I’ve kept a few of them in the past and they were definitely interesting to watch and feed. I would like to try something different this time around. [/B][/B][/B][/B][/B][/B]
