Coleus's 155 bowfront tank. HRV installed and new mixing station

[Coleus]

Got some time today to snap some more pictures and new clam just bought.

Also got some picture of golden angel which i rarely see

This clam opens right away, is it bad or good sign?



One of my favorite fish, very active and friendly



Don't see this one out very often





and here is another modest citizen


is my fish too fat? you be the judge
