Custom Betta fish Tanks

Hey, Eileen here. Ever have a certain look or item in mind for your home or wardrobe or aquarium, and were not able to find just what you wanted? Ever decide to just make it instead? Despite the huge selection of aquarium ornaments on the market today, this DIY approach is what many aquarists are beginning to turn to when the ornaments in the stores just aren’t personal enough for their own unique tanks. So, how can you get in on the action to make your tank truly your own? Here are a few tips to making your own aquarium ornaments or using non-aquarium items to personalize your aquarium.

Silicone Sealant is Your Friend

Silicone aquarium sealant can be found in almost any fish store and is usually available in clear or black. Sealants designed for aquariums are safe for fish and aquarium tankmates when fully cured, but stay away from other sealants like those used for bathroom or hardware applications. You can use sealants to make caves from pieces of rock or rubble, glue shells, stones or other decorations together, or even to cover things like PVC or plastic “caves” with substrate or rocks to form a more natural-looking hideaway. Note: The tank in these photos has a custom background created by arranging and attaching layered slate with black silicone. The effect of the rock wall is rather permanent, but impressive as it adds dimension. This background was applied before the tank was set-up.

Think Outside the Box

Most rigid plastic toys, ornaments and figurines are safe for aquariums as long as they are not painted and do not have any sticker decals on them. Make sure the object is well-cleaned and any stickers or adhesives are completely removed. If you aren’t sure if it is painted or printed, try soaking it in water for awhile, then try to scrape the color off with your fingernail. If it comes off, it isn’t safe for your aquarium. You’ll also want to make sure any small pieces are removed or firmly attached with an adhesive like silicone sealants, and make sure nothing is small enough for your fish to eat.
