I have a tailspot blenny that has been in my tank almost a year, since the tank was cycled and ready for fish. Within the next month he was joined by two clowns, and the first group of CUC. Then about a month later a cleaner shrimp.
Blenny is friendly w/the shrimp — lets himself be cleaned sometimes, and also w/the clowns. He pushes hermits and snails off his home rock if they get too close to his barnacle house, but up until now I’ve never seen him full on attack anything.
Three times now since I added a strawberry conch a couple weeks ago I’ve seen him attack it. These attacks happen at night, and when the conch is spotted on a rock, but not anywhere near the blenny’s home rock. So far the conch has only been a bit shaken but unharmed, but I’m starting to get worried that he might hurt it.
Are tailspots known to become aggressive? I was under the impression that they were very peaceful in tanks except with their own kind. I’m not sure if there’s anything I can do in this situation. He appears to get pretty agitated when he spots the conch on any rock at night, attacks, and then swims in and out of his barnacles eyeing it like he’s prepared to strike again.
This all also has me worried about ever adding another fish. I’d hoped to add a pink streaked wrasse at some point, but that fish will be in the rockwork. Kinda afraid now that the blenny thinks the rocks are all his territory. He doesn’t attack the clowns when they come close but they’ve been in the tank together as babies this whole time.
