HELP ABOUT FISH PLEASE!!!

Question
Hi, my name is judy, from ecuador, south america (my english is not so good)

I'm writing a project for my university about a restaurant with asian style, you know, with fish tanks, but I need to know from an expert the next questions (thank you very very much):

1. Can I put in one aquarium fish and lobsters? Are the lobsters going to eat or hurt the fishes? I mean, how many tanks am I going to need? How must I separate them? In one tank lobsters, in other one fishes, in other one shrimps, in other one crabs? Help!!

2. How must I feed them? Do they all eat the same? what frequency?

3.what about the temperature of each tank?

Thank you very much for your help.  

Answer
Hi Judy!!

I'm am very happy to be able to help you with your project! I will do my best to give you the info you were hoping for.
Questions 1: I'm afraid lobsters will try to eat most fish kept with them. Keep in mind unless you ARE doing a saltwater tank, Most Lobsters need a marine (saltwater) setting. It would be best for Lobsters to have an aquarium to themselves and usually they are best kept alone.
They should be kept in a tank as large as possible.
Lobsters need their water quality maintained at very good levels. And for feeding...
Lobsters like raw fish and meat, algae tablets, shrimp pellets, and worms. They are basically scavengers and will eat most meaty foods. But in the wild they do hunt down small sea life in the wild if they can catch them.
Honestly, I am not sure about the temperature of a Lobster tank---But I'm guessing room temperature might be O.k If I can find it out in the future I will let you know.

Are the lobsters you have in mind the kind for eating? (I really hope not).

Question 2: All 3 questions depend on what species of fish, crabs, shrimps you have in mind.
Since your Restaurant will be Asian style, May I suggest some asian fish that would be great for that theme?

The Arowana is a large, slender, usually silver colored fish that makes a magnificent specimen fish for a very large tank (over 100 gallons) since they grow to more than 36 inches. Arowanas are frequently kept in asian style restuarants...
~Arowanas should be fed live and frozen brine shrimp, black worms and prepared food in the petstore when small.
Larger specimens can also be feed prepared food with supplementation of meaty frozen foods for fish.

The Flowerhorn Cichlid also is a excellent fish for asain theme restuarants. These are aggressive fish but with absolutely beautiful coloration---they too need a large tank to themselves.
~Flowerhorns need pelleted food

These two fish should be kept between 75 and 80 degrees with the help of an Aquarium heater. And should be fed about twice a day no more than they can eat in 30 seconds.

These two fish are NOT compatible by the way.

When you speak of shrimps do you mean saltwater or freshwater? I am really only best experienced in the freshwater catergory. Ghost shrimp, Amano shrimp, and Singapore shrimp just to name a few. Most of these shrimp, particularly the ghost (Also known as Glass Shrimp) can live in most freshwater aquariums with good water quality but must only be kept with small peaceful fish species such as small tetras, Harlequin Rasboras, Fancy guppies, corydoras catfish and other fish that are too small to eat the shrimp. A temperature of 70-80 degrees is fine for them. And can be fed any standard aquarium foods with plenty of algae wafers or tablets, and frozen fish foods.

Crabs are another story it all depends on the species but generally red-claw crabs and fiddler crabs are totally aquatic animals... They do best in their own habitat in a decent sized aquarium with shallow water. They should have the choice to get out of the water by placing large rocks for them to creep up onto. I'm not certain of the species available in your area but the ones around here will eat just about anything such as frozen foods and most fish foods. Some crabs will quarrel among themselves. So one square foot of bottom area per crab is fine.
They are usually too slow to catch most fish but may wave their claws at fish.  Crabs should be fed at the same ratio of that of fish. Most crabs can live in an aquarium without a heater but prefer a temperature of 75-80 degrees.
Crabs will frequently attempt to escape their tank!

This is just a brief overview of the species you mentioned. I hope this helps somewhat. Please give me more specific info if you can on the species and everything else.

If I have missed anything or if you have anymore questions, feel free to email me as you like!

Good luck!

Happy fishkeeping!
