Ok, back on topic, slightly...
As far as the cowfish and the toxin goes, anything I've ever read said that they can release the toxin if stressed or upon death. I've been trying to some anecdotal information to support that claim of "if stressed" part, because I did find people saying that it wiped out their tank when it died, but had trouble finding anything supporting the "if stressed" part of that. I did find this from aquarium advice.com forum from 2004,
So I guess just keep a close eye on him if he ever starts looking off or like he might not be feeling well, so you can protect all your little or not so little guys.I had a Cow one time and he and all the fish were doing fine for a long time. Then one day, there all dead, come to find out if the cow gets sick or for whatever reason poisons the tank and killed everything. Real bummer. Be careful I had to hand feed him, because he so slow at swimming.
And back on topic for real...
I'm looking back and PP said she had a wartskin frogfish, and that it may need to be fed damselfish for its entire life, but that it lived with a toby.
And OMG are they cute, or what??!!!
