AboutNick Expertise I can answer virtually any question relating to freshwater aquariums. I specialize in everything and anything to do with planted and unplanted community tanks, from stocking and compatibility to technical, plant care, set-up and maintenence. I have experience with all kinds of fish and have cared at one point or another for almost every kind of freshwater tank through the years. I can also help find you the best equipment and foods for your money. There are certain products that are useless, and ones that are great, usually the only way to find out is to try them, and I have tried them all.
--If you are having problems with your goldfish, and they are in a tank under 30 gallons please do not bother me with your question. The answer to any question relating to goldfish in tanks under 30 gallons is yes, they do have disease, no they will not live long in a tank that size.
Experience I have been keeping fish since I was 6, I have numerous tanks set up right now and I am the department head of the fish section at a local pet store.
Question QUESTION: My julii cory (female) has been digging uder rock for the past few days and staying there for about 5 hours a day and I've been cheaking for eggs but there no eggs do you know what she's doing
ANSWER: Hello!
Is probably scared and looking for a place to hide. Cories do not like bright lights, and they need a dark place, whether it be under a log or in a hole, to hide for most of the day.
If she were laying eggs, they would not be in the gravel. Cories lay eggs on stuff. On the glass, on plant leaves, or any decor. Their favourite place to lay eggs is on the leaves of the Amazon Sword plant.

QUESTION: But our tank is only a 5 gallon tank and we have a male Julii but he's not scared scared and our tank is full of things so should we take few things out or just leave it like it is
Answer Ah, the problem comes into focus.
Cories are schooling fish, and should be kept in schools of no less than 6-8 individuals in tanks no less than 30" in length. That would be a 20 gallon long or a 30 gallon standard.
When they are kept in such small schools, they will be perpetually scared and will not live a full life span. Eventually they will get more used to the tank and come out more, but if you want to keep these fish properly I would upgrade.
Until then, provide as much hiding as possible, and plenty of live plants.
