Quick question.

Want to add a fair few more rocks to the tank. Do people just stack them up and allow them to lean against the back of the tank? Or when stacking them do you put something between the rocks and the glass?

Basically I have some holey rock along the bottom of the tank, and since I have african cichlids, I'd like to build up the the height of the rocks.

Cheers.

Hi Essjay, what i tend to do is place slate under my gravel (solid bedding which wont crack the base glass) then refill gravel around the base to secure them firmly from digging cichlids and if i need them high i'd generally advise silicone to hold them together (last thing you want is a digging cichlid to disturb your pile and wake up to a smashed pane in your tank and water all over the floor) just remember safety first at all times... silicone is excellent for this peace of mind

Hi Seamus,

Yeah I have some plastic stuff on the bottom of the tank but what do people use to protect the back of the tank and lean rocks against it?

Cheers

generally i would not recomend putting it against the glass(stress fractures) so again use silicone to build your height and simply place in the tank, if it has to be placed against the back glass i'd put a blob of silicone on any part of the rock that would touch the glass to act as a cushion.. hope this helps

i know there exspensive but would a back to nature backround do the job here
