Hello Cathy,
I looked into your photo gallery and I saw this fishes (scientific and german):
Pterophyllum scalare - Skalare or Segelflosser
Gymnocorymbus ternetzi - Trauermantelsalmler
Cleithracara maronii - Maronibuntbarsch
Trichogaster trichopterus - Goldguramie or Goldener Fadenfisch
Phenacogrammus interruptus - Kongosalmler
Poecilia reticulata - Guppy
Xiphophorus maculatus - Platy
Is this right?
The other fishes are not to recognize. The photos are to small.
