But the Cleaner wrasse "according to research" is difficult
Minimum Tank Size: 50 gallons
Care Level: Difficult
Max. Size In Aquarium: Up to 4"
Color Form: Black, Silver, White
Temperament: Peaceful
Reef Compatible: Yes
Diet: Carnivore
In an aquarium 50 gallons or larger, it needs to be kept with a large number of community fish which it can clean and thus obtain food. It "MAY" accept substitute foods such as chopped seafoods, brine shrimp, and live black worms. It should be fed at least three times daily. This species of Cleaner Wrasse is more hardy than the others, but is still difficult to feed and maintain, and should only be kept by experienced aquarists.
I couldnt find an eibli angle only a "tang"
Minimum Tank Size: 70 gallons
Care Level: Moderate
Max. Size In Aquarium: Up to 7"
Color Form: Black, Yellow, Orange
Temperament: Semi-aggressive
Reef Compatible: Yes
Diet: Herbivore
As you see it needs 70 gallons.
70-gallon or larger aquarium is necessary to provide plenty of swimming room. It is extremely aggressive towards other Tangs or Surgeonfish, especially those similar in form and color, and should be the only one in the tank except for in very large systems. Introduce all different species of tangs at one time if more than one is to be maintained in the same aquarium.
Although Tangs will eat meaty foods along with the other fish in the aquarium, it is important that they are offered plenty of marine based seaweed and algae. This will strengthen their immune system, reduce aggression and improve their overall health. Offer dried seaweed tied to a rock or use a lettuce clip, and feed at least 3 times per week. Sea Veggies, Seaweed Salad and Ocean Nutrition are all ideal products and are very easy to use.
