Quick question for the more experienced wrasse keepers. I'm looking at the Fairy wrasse compatibility chart and was wondering would it be a bad idea to try to keep C. bathyphilus with C. Isosceles?
They should do fine. I have the following in my 75 gallon without any issues:
C. bathyphilus
C. isosceles
C. rhomboidalis
H. iridis
H. timorensis
They share the tank with a variety of other fish. Also had a C. finifenmaa (found a since sealed hole and jumped out unfortunately) and a C. lineatus (slowly wasted away, refusing all foods even though it wasn't bullied, and was always out and about). Both C. isosceles and C. bathyphilus are pretty mellow fairies and get along pretty well with most others.
I'd avoid the following if looking to mix in anything smaller than a massive tank from my own experiences with fairies:
C. rubripinnis (chased all the other fairies, even in a 380 gallon tank)
C. katherinae (my current specimen even chases the damsels...)
C. briangreenei (unless you've got a tank 180 gallons or larger, don't mix it with other fairies)
C. scottorum (unless you've got a huge tank, it'll fight all other fairies)
C. rubrimarginatus (my old one was almost as bad as my rubripinnis)
C. cyanogularis
My most mellow fairies have included:
C. isosceles
C. brunneus
C. bathyphilus
C. lubbocki (both Indo and Cebu variants)
C. finifenmaa
C. rhomboidalis
C. cf cyanopleura
C. solorensis
C. lineatus
C. lunatus
C. rubriventralis
C. solorensis, cyanopleura, temmincki, and ryukyuensis fall somewhere in between, and unfortunately I haven't had the pleasure of keeping any other species yet.
