I keep loosing blennies why??

[huhhh]

I have lost 2 lawnmower blennies in the last 3 months. Both seemed perfectly healthy, no marks, or spots, behaved normally, and ate normally. The last one died today. I may have found something on his right side gills (greenish coloring) I can't tell if it's anything or not. Pics may be too small to tell:





The other possibility is a royal dottyback. Doesn't bother my clown or Val puffer at all. But there is a reason only the long skinny fish are dying.

Would a starry blenny be better (different color) or would it matter.

Looks pretty skinny.

Do you have a lot of algae for them to snack on? When you say eating normally, what is it eating?

 

[huhhh]

Constantly grazing on the rocks and sometimes glass. There's not a huge amount of algae but it's visible on some substrate and parts of the glass. The previous blenny was bigger and also ate pellets and krill as well as grazing. That one got a bit discolored (lighter) before it died. This last one looked fine, until it was dead.

BTW this is a 46 bow tank.

Use any Vortechs without the sponge guards? I unfortunately lost a couple blennies to my MP10s before figuring out what’s as going on.

 

[huhhh]

No, nothing that strong. The return is supposed to put out around 500 gph (but probably less). The other powerhead I have pretty small, only rated for a tank half the size, I just use it to keep things moving in the corner the return doesn't reach.

Probably not enough to eat.

Have you tried Nori?
